Custom Drawn Controls advances

[lainz]

Felipe there is a way to access all properties of a control?

Because I'm trying to add new buttons in the same drawer.

I already added:

Code: [Select]

type
  TWin7ButtonStyle = (bsNone, bsArrowLeft, bsArrowRight);

  TCDButton = class(customdrawncontrols.TCDButton)
  public
    property Win7Style: TWin7ButtonStyle;
  end;   
To use in this way:

Code: [Select]

CDButton5.Win7Style := bsArrowLeft;
But in the drawer I can't acces the property =)

There is a separation to make the drawers independent from changes in the controls. To add more info do like this:

  TMyCDButton...
  protected
    procedure CreateControlStateEx; override;
    procedure PrepareControlStateEx; override; // <-- Check how controls in customdrawncontrols.pas do those overrides

  TMyCDButtonStateEx = class(TCDButtonStateEx) // TCDButtonStateEx comes from customdrawndrawers.pas
  public
    whatever extra info
  end;

And in the drawer you can use the is operator to check if the stateex is your extended version and then cast to it.

Thankyou.

ok this will be useful to create a custom drawn bgrabutton.

since those special buttons do not use caption I chose not to make a new control and left them in extra1 =) changing from one style to other with caption (for now).

First of all, customdrawn lcl is great beginning.

IMO when it will be mature enough, there just will be no
need it other widgetsets.

I hope to see lazarus drawn with it some day.
Close buttons on editor tabs, that's what I wanted under win

My question is:

Can controls be rendered with hardware support (where available) ?
I mean like FireMonkey in Delphi ? What's better way to implement it ?

The architecture was created thinking about this, but is not currently implemented. New backends would be required for this, for example a backend for OpenGL, OpenGL ES and/or DirectX.

Can you please describe just brief steps how this can be done or link to wiki.
I'd like to try myself to create some h/w accelerated controls.
Need a point to start from.

You have to read and familiarize yourself with the source code of LCL-CustomDrawn:

http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/lcl/interfaces/customdrawn/?root=lazarus

There is a define for each backend. You need to add a new backend and implement everything necessary.

Можно ли на форму с Custom Draw Widget рисовать openGL окно или нужно создавать свое окно?
Is it possible to form with Custom Draw Widget drawing openGL window or need to create its own window?

Support for a sub-window with OpenGL support is possible but currently not implemented.

Hi Felipe, how I can enable the debug VerboseCDPaintProfiler? And how I can read the output of that.

Code: [Select]

And here debug information defines:
VerboseCDPaintProfiler - Adds profiling information to indicate how fast the paint event is processed

[felipemdc]

Define it in the file lcl/interfaces/customdrawn/customdrawndefines.inc

[lainz]

It's already defined, but how I can read the output of that?

[felipemdc]

In the console, like always. If you are in Windows uncheck the option "win32 graphical program" (or similar name) in the Project Options dialog

Hello, I'm testing TCDPageControl, when I use nboShowCloseButton the close button placed incorrectly if TCDTabSheets caption length are not equal.
Any one realize this?
