Basic graphic primitives split into GraphType package, so that we can reference it from interface (GTK, Win32) units. New Frame3d canvas method that uses native (themed) drawing (GTK only). New overloaded Canvas.TextRect method. LCLLinux and Graphics was split, so a bunch of files had to be modified. Revision 1.16 2002/01/01 15:50:13 lazarus MG: fixed initial component aligning Revision 1.15 2001/12/21 18:16:59 lazarus Added TImage class Shane Revision 1.14 2001/11/05 18:18:19 lazarus added popupmenu+arrows to notebooks, added target filename Revision 1.12 2001/06/26 21:44:32 lazarus MG: reduced paint messages Revision 1.11 2001/06/12 18:31:01 lazarus MG: small bugfixes Revision 1.10 2001/04/17 21:39:17 lazarus + added working OnClick support for TCustomRadiogroup, stoppok Revision 1.9 2001/04/06 22:28:09 lazarus * TTimer uses winapi interface now instead of sendmessage interface, stoppok Revision 1.8 2001/03/15 14:42:20 lazarus MG: customradiogroup is now streamable Revision 1.7 2001/01/12 18:27:31 lazarus Streaming additions by MAttias Shane Revision 1.6 2001/01/09 21:06:06 lazarus Started taking KeyDown messages in TDesigner Shane Revision 1.5 2001/01/09 18:23:20 lazarus Worked on moving controls. It's just not working with the X and Y coord's I'm getting. Shane Revision 1.4 2001/01/05 18:56:23 lazarus Minor changes Revision 1.3 2001/01/04 20:33:53 lazarus Moved lresources. Moved CreateLFM to Main.pp Changed Form1 and TFOrm1 to MainIDE and TMainIDE Shane Revision 1.2 2000/12/29 15:04:07 lazarus Added more images to the resource. Shane Revision 1.1 2000/07/13 10:28:23 michael + Initial import Revision 1.25 2000/06/29 21:06:14 lazarus reintroduced TAbstractReader=Treader hack, stoppok Revision 1.24 2000/06/28 13:11:37 lazarus Fixed TNotebook so it gets page change events. Shane Revision 1.23 2000/05/08 23:59:52 lazarus Updated my email address in the documentation to the current one. Also removed email references in comments that were not @author comments to fix problems with the documentation produced by pasdoc. CAW Revision 1.22 2000/02/26 23:31:50 lazarus MWE: Fixed notebook crash on insert Fixed loadfont problem for win32 (tleast now a fontname is required) Revision 1.21 2000/01/10 19:09:18 lazarus MWE: Removed temp hack TAbstractReader=TReader. It is now defined Revision 1.20 2000/01/10 00:07:12 lazarus MWE: Added more scrollbar support for TWinControl Most signals for TWinContorl are jet connected to the wrong widget (now scrolling window, should be fixed) Added some cvs entries Revision 1.19 2000/01/07 21:14:13 lazarus Added code for getwindowlong and setwindowlong. Shane Revision 1.18 2000/01/06 01:10:36 lazarus Stoppok: - changed ReadState to match current definition in fcl (affects TPage & TCustomNotebook) - added callback FItems.OnChanging to TCustomRadiogroup Revision 1.17 2000/01/02 00:22:54 lazarus stoppok: - introduced TBevel - enhanced TCustomRadioGroup Revision 1.16 1999/12/31 02:20:57 lazarus Initial implementation of TCustomRadioGroup / TRadioGroup stoppok Revision 1.15 1999/11/01 01:28:29 lazarus MWE: Implemented HandleNeeded/CreateHandle/CreateWND Now controls are created on demand. A call to CreateComponent shouldn't be needed. It is now part of CreateWnd Revision 1.14 1999/10/22 21:01:50 lazarus Removed calls to InterfaceObjects except for controls.pp. Commented out any gtk depend lines of code. MAH Revision 1.13 1999/10/19 19:16:51 lazarus renamed stdcontrols.pp stdctrls.pp Shane Revision 1.12 1999/10/04 23:36:25 lazarus Moved PageList and Page property to public to allow access to them. CAW Revision 1.11 1999/09/30 21:59:01 lazarus MWE: Fixed TNoteBook problems Modifications: A few - Removed some debug messages + Added some others * changed fixed widged of TPage. Code is still broken. + TWinControls are also added to the Controls collection + Added TControl.Controls[] property Revision 1.10 1999/09/22 19:09:17 lazarus Added some trace info for the TNotebook problem. Revision 1.9 1999/09/21 23:46:54 lazarus *** empty log message *** Revision 1.8 1999/09/16 21:14:27 lazarus Some cleanups to the timer class. (moved some comments to timer.inc, added more comments and changed TTimer.Timer from function to procedure) Stoppok Revision 1.7 1999/09/13 03:27:10 lazarus Fixed a bug in the PageIndex property of TCustomNotebook where it was not tracking notebook pages if the user selected them with the mouse in a TTabbedNotebook. caw Revision 1.6 1999/08/26 23:36:02 peter + paintbox + generic keydefinitions and gtk conversion * gtk state -> shiftstate conversion Revision 1.5 1999/08/04 05:21:11 lazarus Created TCustomNotebook to allow both TNotebook and TTabbedNotebook to inherit from a common object. Made TNotebook work like Delphi TNotebook. Revision 1.3 1999/07/31 06:39:22 lazarus Modified the IntSendMessage3 to include a data variable. It isn't used yet but will help in merging the Message2 and Message3 features.
