BGRA Controls

Hi Lainz!

Regarding the demo, coasting says he's taking care of posting new updates. So I would rather let him use this code.

I am not sure about changing the reference to BGRABitmap4LCL_OpenGL package in general, because this does the following:
- imposes RGBA order on bitmaps (which is a bit slower on windows)
- adds a dependency to lazopenglcontext package

For people who don't use OpenGL, it is better to keep the regular version. I don't know if there is an easy solution. For now, I would say that people need to change the reference in BGRAControls package to either BGRABitmap or BGRABitmap4LCL_OpenGL depending on their needs. If they are going to use BGRABitmap4LCL_OpenGL package (for TBGLVirtualScreen and OpenGL functions), then they need to change the reference in BGRAControls package accordingly.

Ok, so it is slower on windows, well i'm reverting the changes now

[circular]

Yes, apologies.

I am thinking in fact that maybe with OpenGL we could use the same channel order (BGRA for Windows and RGBA for Linux) and simply swap when sending textures to OpenGL. Indeed the gain of speed with OpenGL is only when keeping the same textures and avoiding any transfer of textures so the swaping of red and blue is not very important for that.

Still the package for OpenGL would depend on lazopenglcontext package.

But we need a better way to manage these situations like we talked before.

[circular]

Yes. Well the thing is the pixel format is defined by the record TBGRAPixel so it is not possible to compile two versions with a different definition of it within the same program.

I am thinking maybe to split things differently. Like putting the maximum of the OpenGL stuff in the main BGRABitmap package, and add other packages that plug into this one. And so the OpenGL package would use the usual TBGRAPixel. As said before, it does not really matter because textures are loaded once, swapping red/blue does not matter much for the framerate.

[aradeonas]

It seems a better solution.

Hi, I'm releasing BGRA-Controls v3.8

• Added BCButtonFocus
• Added BCRadialProgressBar
• Added BGRA Ribbon Custom
• Minor fixes

Download it here:
https://github.com/bgrabitmap/bgracontrols/releases

[lainz]

I'm updating the Git repository with new stuff:
- Added fpGUI theme (Windows 8 / 10 like) is a draft and I think I'm not updating this anymore, doesn't worth, use LCL default if you need native
- Added Plugins test in extra folder, how to create a dll to add third party functionality to a virtual screen
- Added material design animation test in extra folder, how to create a button with material design animation like

Edit: Added material design button component

Get it here:

Hi Lainz,
Went to try Version 4 ( Laz 1.3, fpc 2.7.1 on Windows)
and I get
bgracontrols-4.0\bgracustomdrawn.pas(61,15) Error: There is no method in an ancestor class to be overridden: "DrawButton(TFPCustomCanvas;POINT;SIZE;TCDControlState;TCDButtonStateEx);"

Same error using Laz 1.4.4 on OSX

Is the update only for FPC 3 and above?

I'm using it with Lazarus 1.6 and Lazarus trunk. If you can't compile you can:
- Remove that unit from the package.
- Update all custom drawn units (note that are a lot, not only these included in the customdrawn package, see the folder LCL for example).

Hi Lainz,

I can't compile the package to install it.

Is it now only for Laz 1.6/1.7 with FPC 3.0.0 or above?

Maybe customdrawn is not available in older versions of lazarus?

Try the BGRAControls 3.8/3.9 is available for download on github, you will get everything except the new Custom Drawn ones.

PD: I forget, in 3.9 and newer there is a new dependency with LazUTF8, maybe is not available in older lazarus too.

@Lainz,@circular, i just want to write to thank you for the time, effort and a lot of knowledge you put into FPC. And give us new tools to developers.

Many others thanks.
