Features:
- dnd docking
- preview rectangle while drag over
- inside and outside docking
- header with close button and hints
- using stock item for close button glyph
- auto header caption from content
- hide header caption for floating form
- auto site for headers to safe space (configurable)
- bidimode for headers
- page docking
- pagecontrols uses TPageControl for native look&feel
- page control is automatically removed if only one page left
- scaling on resize (configurable)
- auto insert splitters between controls (size configurable)
- keep size when docking
- header is automatically hidden when docked into page
- save complete layout
- restore layout:
- close unneeded windows,
- automatic clean up if windows are missing,
- reusing existing docksites to minimize flickering
- popup menu
- close site
- lock/unlock
- header auto, left, top, right, bottom
- undock (needed if no place to undock on screen)
- merge (for example after moving a dock page into a layout)
- enlarge side to left, top, right, bottom
- move page left, right, leftmost, rightmost
- close page
- tab position (default, left, top, right, bottom)
- options
- dock site: MakeDockSite for forms, that should be able to dock other sites,
but should not be docked themselves. Their Parent is always nil.
- design time package for IDE
- dnd move page index
- dnd move page to another pagecontrol
- on close button: save a restore layout
- option to show/hide dock headers
- option HeaderStyle to change appearance of grabbers
ToDo:
- option to save on IDE close (if MainForm is visible on active screen)
- restore: put MainForm on active screen
- restore custom dock site splitter without resizing content, only resize docked site
- undock on hide
- popup menu
- shrink side left, top, right, bottom
- implement a simple way to make forms dockable at designtime without any code
- on show again (hide form, show form): restore layout
- close button for pages
- event for drawing grabbers+headers
- save/restore other splitters
Parent bug with links to all other:
- http://bugs.freepascal.org/view.php?id=18298 default layout sometimes wrong main bar
Other bugs:
- http://bugs.freepascal.org/view.php?id=19810 multi monitor
