FIXME:

|
|
Text layout needs a lot of work. Plain drawText is useful but too
|
|
limited. It will need some kind of text context thing which it will
|
|
update and you can pass it on and get more details out of it.
|
|
|
|
It will need a bounding box, a current cursor location that is updated
|
|
as drawing continues, and various changable facts (which can also be
|
|
changed on the painter i guess) like font, color, size, background,
|
|
etc.
|
|
|
|
We can also fetch the carat location from it somehow.
|
|

Should prolly be an overload of drawText

simpledisplay.d provides basic cross-platform GUI-related functionality,
|
|
including creating windows, drawing on them, working with the clipboard,
|
|
timers, OpenGL, and more. However, it does NOT provide high level GUI
|
|
widgets. See my minigui.d, an extension to this module, for that
|
|
functionality.
|
|
|
|
simpledisplay provides cross-platform wrapping for Windows and Linux
|
|
(and perhaps other OSes that use X11), but also does not prevent you
|
|
from using the underlying facilities if you need them. It has a goal
|
|
of working efficiently over a remote X link (at least as far as Xlib
|
|
reasonably allows.)
|
|
|
|
simpledisplay depends on [arsd.color|color.d], which should be available from the
|
|
same place where you got this file. Other than that, however, it has
|
|
very few dependencies and ones that don't come with the OS and/or the
|
|
compiler are all opt-in.
|
|
|
|
simpledisplay.d's home base is on my arsd repo on Github. The file is:
|
|
https://github.com/adamdruppe/arsd/blob/master/simpledisplay.d
|
|
|
|
simpledisplay is basically stable. I plan to refactor the internals,
|
|
and may add new features and fix bugs, but It do not expect to
|
|
significantly change the API. It has been stable a few years already now.

|
The goal here is to give some complete programs as overview examples first, then a look at each major feature with working examples first, then, finally, the inline class and method list will follow.
|
|
|
|
Scan for headers for a topic - $(B they will visually stand out) - you're interested in to get started quickly and feel free to copy and paste any example as a starting point for your program. I encourage you to learn the library by experimenting with the examples!
|
|
|
|
All examples are provided with no copyright restrictions whatsoever. You do not need to credit me or carry any kind of notice with the source if you copy and paste from them.
|
|
|
|
To get started, download `simpledisplay.d` and `color.d` to a working directory. Copy an example info a file called `example.d` and compile using the command given at the top of each example.

If you need help, email me: destructionator@gmail.com or IRC us, #d on Freenode (I am destructionator or adam_d_ruppe there). If you learn something that isn't documented, I appreciate pull requests on github to this file.
|
|
|
|
At points, I will talk about implementation details in the documentation. These are sometimes
|
|
subject to change, but nevertheless useful to understand what is really going on. You can learn
|
|
more about some of the referenced things by searching the web for info about using them from C.
|
|
You can always look at the source of simpledisplay.d too for the most authoritative source on
|
|
its specific implementation. If you disagree with how I did something, please contact me so we
|
|
can discuss it!

$(H2 Topics)

|
$(H3 $(DDOC_ANCHOR topic-windows) Windows)
|
|
The $(LREF SimpleWindow) class is simpledisplay's flagship feature. It represents a single
|
|
window on the user's screen.
|
|
|
|
You may create multiple windows, if the underlying platform supports it. You may check
|
|
`static if(multipleWindowsSupported)` at compile time, or catch exceptions thrown by
|
|
SimpleWindow's constructor at runtime to handle those cases.
|
|
|
|
A single running event loop will handle as many windows as needed.

|
|
|
$(H3 $(DDOC_ANCHOR topic-event-loops) Event loops)
|
|
The simpledisplay event loop is designed to handle common cases easily while being extensible for more advanced cases, or replaceable by other libraries.
|
|
|
|
The most common scenario is creating a window, then calling `window.eventLoop` when setup is complete. You can pass several handlers to the `eventLoop` method right there:
|
|
|
|
---
|
|
// dmd example.d simpledisplay.d color.d
|
|
import simpledisplay;
|
|
void main() {
|
|
auto window = new SimpleWindow(200, 200);
|
|
window.eventLoop(0,
|
|
delegate (dchar) { /* got a character key press */ }
|
|
);
|
|
}
|
|
---
|
|
|
|
$(TIP If you get a compile error saying "I can't use this event handler", the most common thing in my experience is passing a function instead of a delegate. The simple solution is to use the `delegate` keyword, like I did in the example above.)
|
|
|
|
On Linux, the event loop is implemented with the `epoll` system call for efficiency an extensibility to other files. On Windows, it runs a traditional `GetMessage` + `DispatchMessage` loop, with a call to `SleepEx` in each iteration to allow the thread to enter an alertable wait state regularly, primarily so Overlapped I/O callbacks will get a chance to run.
|
|
|
|
On Linux, simpledisplay also supports my `arsd.eventloop` module. Compile your program, including the eventloop.d file, with the `-version=with_eventloop` switch.
|
|
|
|
It should be possible to integrate simpledisplay with vibe.d as well, though I haven't tried.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-notification-areas) Notification area (aka systray) icons)
|
|
Notification area icons are currently only implemented on X11 targets. Windows support will come when I need it (or if someone requests it and I have some time to spend on it).
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-input-handling) Input handling)
|
|
There are event handlers for low-level keyboard and mouse events, and higher level handlers for character events.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-2d-drawing) 2d Drawing)
|
|
To draw on your window, use the `window.draw` method. It returns a $(LREF ScreenPainter) structure with drawing methods.
|
|
|
|
Important: `ScreenPainter` double-buffers and will not actually update the window until its destructor is run. Always ensure the painter instance goes out-of-scope before proceeding. You can do this by calling it inside an event handler, a timer callback, or an small scope inside main. For example:
|
|
|
|
---
|
|
// dmd example.d simpledisplay.d color.d
|
|
import simpledisplay;
|
|
void main() {
|
|
auto window = new SimpleWindow(200, 200);
|
|
{ // introduce sub-scope
|
|
auto painter = window.draw(); // begin drawing
|
|
/* draw here */
|
|
painter.outlineColor = Color.red;
|
|
painter.fillColor = Color.black;
|
|
painter.drawRectangle(Point(0, 0), 200, 200);
|
|
} // end scope, calling `painter`'s destructor, drawing to the screen.
|
|
window.eventLoop(0); // handle events
|
|
}
|
|
---
|
|
|
|
Painting is done based on two color properties, a pen and a brush.
|
|
|
|
At this time, the 2d drawing does not support alpha blending. If you need that, use a 2d OpenGL context instead.
|
|
FIXME add example of 2d opengl drawing here
|
|
$(H3 $(DDOC_ANCHOR topic-3d-drawing) 3d Drawing (or 2d with OpenGL))
|
|
simpledisplay can create OpenGL contexts on your window. It works quite differently than 2d drawing.
|
|
|
|
Note that it is still possible to draw 2d on top of an OpenGL window, using the `draw` method, though I don't recommend it.
|
|
|
|
To start, you create a `SimpleWindow` with OpenGL enabled by passing the argument `OpenGlOptions.yes` to the constructor.
|
|
|
|
Next, you set `redrawOpenGlScene` to a delegate which draws your frame.
|
|
|
|
To force a redraw of the scene, call `window.redrawOpenGlSceneNow()`.
|
|
|
|
Please note that my experience with OpenGL is very out-of-date, and the bindings in simpledisplay reflect that. If you want to use more modern functions, you may have to define the bindings yourself, or import them from another module. However, I believe the OpenGL context creation done in simpledisplay will work for any version.
|
|
|
|
This example program will draw a rectangle on your window:
|
|
|
|
---
|
|
// dmd example.d simpledisplay.d color.d
|
|
import simpledisplay;
|
|
|
|
void main() {
|
|
|
|
}
|
|
---
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-images) Displaying images)
|
|
You can also load PNG images using my `png.d`.
|
|
|
|
---
|
|
// dmd example.d simpledisplay.d color.d png.d
|
|
import simpledisplay;
|
|
import arsd.png;
|
|
|
|
void main() {
|
|
auto image = Image.fromMemoryImage(readPng("image.png"));
|
|
displayImage(image);
|
|
}
|
|
---
|
|
|
|
Compile with `dmd example.d simpledisplay.d png.d`.
|
|
|
|
If you find an image file which is a valid png that `arsd.png` fails to load, please let me know. In the mean time of fixing the bug, you can probably convert the file into an easier-to-load format. Be sure to turn OFF png interlacing, as that isn't supported. Other things to try would be making the image smaller, or trying 24 bit truecolor mode with an alpha channel.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-sprites) Sprites)
|
|
The $(LREF Sprite) class is used to make images on the display server for fast blitting to screen. This is especially important to use to support fast drawing of repeated images on a remote X11 link.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-clipboard) Clipboard)
|
|
The free functions $(LREF getClipboardText) and $(LREF setClipboardText) consist of simpledisplay's cross-platform clipboard support at this time.
|
|
|
|
It also has helpers for handling X-specific events.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-timers) Timers)
|
|
There are two timers in simpledisplay: one is the pulse timeout you can set on the call to `window.eventLoop`, and the other is a customizable class, $(LREF Timer).
|
|
|
|
The pulse timeout is used by setting a non-zero interval as the first argument to `eventLoop` function and adding a zero-argument delegate to handle the pulse.
|
|
|
|
---
|
|
import simpledisplay;
|
|
|
|
void main() {
|
|
auto window = new SimpleWindow(400, 400);
|
|
// every 100 ms, it will draw a random line
|
|
// on the window.
|
|
window.eventLoop(100, {
|
|
auto painter = window.draw();
|
|
|
|
import std.random;
|
|
// random color
|
|
painter.outlineColor = Color(uniform(0, 256), uniform(0, 256), uniform(0, 256));
|
|
// random line
|
|
painter.drawLine(
|
|
Point(uniform(0, window.width), uniform(0, window.height)),
|
|
Point(uniform(0, window.width), uniform(0, window.height)));
|
|
|
|
});
|
|
}
|
|
---
|
|
|
|
The `Timer` class works similarly, but is created separately from the event loop. (It still fires through the event loop, though.) You may make as many instances of `Timer` as you wish.
|
|
|
|
The pulse timer and instances of the $(LREF Timer) class may be combined at will.
|
|
|
|
---
|
|
import simpledisplay;
|
|
|
|
void main() {
|
|
auto window = new SimpleWindow(400, 400);
|
|
auto timer = new Timer(1000, delegate {
|
|
auto painter = window.draw();
|
|
painter.clear();
|
|
});
|
|
|
|
window.eventLoop(0);
|
|
}
|
|
---
|
|
|
|
Timers are currently only implemented on Windows, using `SetTimer` and Linux, using `timerfd_create`. These deliver timeout messages through your application event loop.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-os-helpers) OS-specific helpers)
|
|
simpledisplay carries a lot of code to help implement itself without extra dependencies, and much of this code is available for you too, so you may extend the functionality yourself.
|
|
|
|
See also: `xwindows.d` from my github.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-os-extension) Extending with OS-specific functionality)
|
|
`handleNativeEvent` and `handleNativeGlobalEvent`.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-integration) Integration with other libraries)
|
|
Integration with a third-party event loop is possible.
|
|
|
|
On Linux, you might want to support both terminal input and GUI input. You can do this by using simpledisplay together with eventloop.d and terminal.d.
|
|
|
|
$(H3 $(DDOC_ANCHOR topic-guis) GUI widgets)
|
|
simpledisplay does not provide GUI widgets such as text areas, buttons, checkboxes, etc. It only gives basic windows, the ability to draw on it, receive input from it, and access native information for extension. You may write your own gui widgets with these, but you don't have to because I already did for you!
|
|
|
|
Download `minigui.d` from my github repository and add it to your project. minigui builds these things on top of simpledisplay and offers its own Window class (and subclasses) to use that wrap SimpleWindow, adding a new event and drawing model that is hookable by subwidgets, represented by their own classes.
|
|
|
|
Migrating to minigui from simpledisplay is often easy though, because they both use the same ScreenPainter API, and the same simpledisplay events are available, if you want them. (Though you may like using the minigui model, especially if you are familiar with writing web apps in the browser with Javascript.)
|
|
|
|
minigui still needs a lot of work to be finished at this time, but it already offers a number of useful classes.

I don't have a Mac, so that code isn't maintained. I would like to have a Cocoa
|
|
implementation though.
|
|
|
|
The NativeSimpleWindowImplementation and NativeScreenPainterImplementation both
|
|
suck. If I was rewriting it, I wouldn't do it that way again.

This file must not have any more required dependencies. If you need bindings, add
|
|
them right to this file. Once it gets into druntime and is there for a while, remove
|
|
bindings from here to avoid conflicts (or put them in an appropriate version block
|
|
so it continues to just work on old dmd), but wait a couple releases before making the
|
|
transition so this module remains usable with older versions of dmd.
|
|
|
|
You may have optional dependencies if needed by putting them in version blocks or
|
|
template functions. You may also extend the module with other modules with UFCS without
|
|
actually editing this - that is nice to do if you can.
|
|
|
|
Try to make functions work the same way across operating systems. I typically make
|
|
it thinly wrap Windows, then emulate that on Linux.
|
|
|
|
A goal of this is to keep a gui hello world to less than 250 KB. This means avoiding
|
|
Phobos! So try to avoid it.
|
|
|
|
See more comments throughout the source.
|
|
|
|
I realize this file is fairly large, but over half that is just bindings at the bottom
|
|
or documentation at the top. Some of the classes are a bit big too, but hopefully easy
|
|
to understand. I suggest you jump around the source by looking for a particular
|
|
declaration you're interested in, like `class SimpleWindow` using your editor's search
|
|
function, then look at one piece at a time.

The flagship window class.
|
|
|
|
|
|
SimpleWindow tries to make ordinary windows very easy to create and use without locking you
|
|
out of more advanced or complex features of the underlying windowing system.
|
|
|
|
For many applications, you can simply call `new SimpleWindow(some_width, some_height, "some title")`
|
|
and get a suitable window to work with.
|
|
|
|
From there, you can opt into additional features, like custom resizability and OpenGL support
|
|
with the next two constructor arguments. Or, if you need even more, you can set a window type
|
|
and customization flags with the final two constructor arguments.
|
|
|
|
If none of that works for you, you can also create a window using native function calls, then
|
|
wrap the window in a SimpleWindow instance by calling `new SimpleWindow(native_handle)`. Remember,
|
|
though, if you do this, managing the window is still your own responsibility! Notably, you
|
|
will need to destroy it yourself.
|

class SimpleWindow : CapableOfHandlingNativeEvent {
|
|
/++
|
|
This creates a window with the given options. The window will be visible and able to receive input as soon as you start your event loop. You may draw on it immediately after creating the window, without needing to wait for the event loop to start if you want.
|
|
|
|
The constructor tries to have sane default arguments, so for many cases, you only need to provide a few of them.
|
|
|
|
Params:
|
|
|
|
width = the width of the window's client area, in pixels
|
|
height = the height of the window's client area, in pixels
|
|
title = the title of the window (seen in the title bar, taskbar, etc.). You can change it after construction with the $(LREF SimpleWindow._title) property.
|
|
opengl = $(LREF OpenGlOptions) are yes and no. If yes, it creates an OpenGL context on the window.
|
|
resizable = $(LREF Resizablity) has three options:
|
|
$(P `allowResizing`, which allows the window to be resized by the user. The `windowResized` delegate will be called when the size is changed.)
|
|
$(P `fixedSize` will not allow the user to resize the window.)
|
|
$(P `automaticallyScaleIfPossible` will allow the user to resize, but will still present the original size to the API user. The contents you draw will be scaled to the size the user chose. If this scaling is not efficient, the window will be fixed size. The `windowResized` event handler will never be called. This is the default.)
|
|
windowType = The type of window you want to make.
|
|
customizationFlags = A way to make a window without a border, always on top, skip taskbar, and more. Do not use this if one of the pre-defined $(LREF WindowTypes), given in the `windowType` argument, is a good match for what you need.

Requests attention from the user for this window.

The typical result of this function is to change the color

|
of the taskbar icon, though it may be tweaked on specific

|
platforms.
|
|
|
|
It is meant to unobtrusively tell the user that something
|
|
relevant to them happened in the background and they should

check the window when they get a chance. Upon receiving the

|
keyboard focus, the window will automatically return to its

natural state.

may do nothing, because the user is presumed to already be

$(NOTE If you are writing platform-aware code and need to know low-level details, uou may check `if(Image.impl.xshmAvailable)` to see if MIT-SHM is used on X11 targets to draw `Image`s and `Sprite`s. Use `static if(UsingSimpledisplayX11)` to determine if you are compiling for an X11 target.)
|
|
|
|
Drawing an image to screen is not necessarily fast, but applying algorithms to draw to the image itself should be fast. An `Image` is also the first step in loading and displaying images loaded from files.
|
|
|
|
If you intend to draw an image to screen several times, you will want to convert it into a $(LREF Sprite).
|
|
|
|
$(IMPORTANT `Image` may represent a scarce, shared resource that persists across process termination, and should be disposed of properly. On X11, it uses the MIT-SHM extension, if available, which uses shared memory handles with the X server, which is a long-lived process that holds onto them after your program terminates if you don't free it.
|
|
|
|
It is possible for your user's system to run out of these handles over time, forcing them to clean it up with extraordinary measures - their GUI is liable to stop working!
|
|
|
|
Be sure these are cleaned up properly. simpledisplay will do its best to do the right thing, including cleaning them up in garbage collection sweeps (one of which is run at most normal program terminations) and catching some deadly signals. It will almost always do the right thing. But, this is no substitute for you managing the resource properly yourself. (And try not to segfault, as recovery from them is alway dicey!)
|
|
|
|
Please call `destroy(image);` when you are done with it. The easiest way to do this is with scope:
|
|
|
|
---
|
|
auto image = new Image(256, 256);
|
|
scope(exit) destroy(image);
|
|
---
|
|
|
|
As long as you don't hold on to it outside the scope.
|
|
|
|
I might change it to be an owned pointer at some point in the future.
|
|
|
|
)
|
|
|
|
Drawing pixels on the image may be simple, using the `opIndexAssign` function, but
|
|
you can also often get a fair amount of speedup by getting the raw data format and
|
|
writing some custom code.

/**
|
|
Sprites are optimized for fast drawing on the screen, but slow for direct pixel
|
|
access. They are best for drawing a relatively unchanging image repeatedly on the screen.
|
|
|
|
|
|
On X11, this corresponds to an `XPixmap`. On Windows, it still uses a bitmap,
|
|
though I'm not sure that's ideal and the implementation might change.
|
|
|
|
You create one by giving a window and an image. It optimizes for that window,
|
|
and copies the image into it to use as the initial picture. Creating a sprite
|
|
can be quite slow (especially over a network connection) so you should do it
|
|
as little as possible and just hold on to your sprite handles after making them.
|
|
simpledisplay does try to do its best though, using the XSHM extension if available,
|
|
but you should still write your code as if it will always be slow.
|
|
|
|
Then you can use `sprite.drawAt(painter, point);` to draw it, which should be
|
|
a fast operation - much faster than drawing the Image itself every time.
|
|

`Sprite` represents a scarce resource which should be freed when you
|
|
are done with it. Use the `dispose` method to do this. Do not use a `Sprite`
|
|
after it has been disposed. If you are unsure about this, don't take chances,
|
|
just let the garbage collector do it for you. But ideally, you can manage its
|
|
lifetime more efficiently.
|
|
|
|
$(NOTE `Sprite`, like the rest of simpledisplay's `ScreenPainter`, does not
|
|
support alpha blending in its drawing at this time. That might change in the
|
|
future, but if you need alpha blending right now, use OpenGL instead. See
|
|
`gamehelpers.d` for a similar class to `Sprite` that uses OpenGL: `OpenGlTexture`.)
|
|
|
|
FIXME: you are supposed to be able to draw on these similarly to on windows.
|
|
ScreenPainter needs to be refactored to allow that though. So until that is
|
|
done, consider a `Sprite` to have const contents.
