- {: The Simple Paint Program using Gui components from GLScene.
- To use the Gui you must place a TGLGUILayout component on your form,
- this is a storage for Gui layouts within a single texture, each layout
- is identified by a name. All Layouts can be used with any Gui Component,
- however features like a forms title might look awkward on a checkbox...
- For correct usage a Material Library should be used.
- If a BitmapFont or WindowsFont is applied to a layout it is auto set to
- the components, however it is perfectly valid to set it to someother font.
- To Interface correctly, handlers must send the mouse and key events
- to a root gui component, this can be any of the keyboard aware gui
- components or a RootControl(a tramsparent component with no other purpose)
- Plus the root gui component should have its DoChanges invoked, this
- makes form movement and other mouse/key events changes fluintly
- match the rendering process, eg no flicker.
- All other Gui component must be below the root control in the GLScene
- hierachy, this is a rule which allows you to seperate gui from the
- rest of glscene and save some clock cycles on <tab> operations.
- Plus mouse events...
- For a more thorough look on the gui please check out my article on
- the caperaven site: http://caperaven.co.za
- under "Online documentation" called "Gui Interface"
- The two BMP's pen.bmp and brush.bmp have been published by Borland in the
- Doc/GraphEx demo that comes with Delphi.
- The rest is MPL as part of the GLScene project.
- NOTICE IS YOU HAVE A LOW FRAME RATE and you feel the drawing is lagging to
- far behind, try setting GLCanvas.MaxInvalidRenderCount to a lower value in
- the formcreate event.
- <b>History : </b><font size=-1><ul>
- <li>10/11/12 - PW - Changed FPS output to miFPS.Caption instead of Form1.Caption
- <li>01/05/03 - JAJ - Creation
- </ul></font>
- }
- program GuiPaint;
- uses
- Forms,
- fGuiPaint in 'fGuiPaint.pas' {FormGuiPaint};
- {$R *.RES}
- begin
- Application.Initialize;
- Application.CreateForm(TFormGuiPaint, FormGuiPaint);
- Application.Run;
- end.
