This is the way that Windows draws controls with active theme.
Oh yes, I could use the functions:
OpenThemeData()
DrawThemeBackground()
DrawThemeText()
CloseThemeData()
But in this way I can not draw rounded/circular buttons.
It seems to me that the simplest solution of the colored buttons will be adding in HMG two properties for standard buttons:
TEXTCOLOR
BACKCOLOR
and processing WM_NOTIFY/NM_CUSTOMDRAW message.

The problem of this type of solution is that departs from the normal behavior of Windows with active theme.

Beautiful, perfect !
There's only one thing I'd like you to change: Is it possible to transform RGB color into HexaDecimals ? (Because we are accustomed RGB in array with the three elements). As for aesthetics, IMHO You do not have to change anything !
I liked it a lot and I would definitely use it in my applications when you need differentiated buttons.
Thank you very much, Mr. Krzysztof, great work !

Very Good Job!!!
It works but during the compilation I have plenty of warnings :
OwnButtonDemo.prg(383) Warning W0002 Ambiguous reference, assuming memvar '_HMG_SYSDATA'
....
OwnButton.prg(95) Warning W0002 Ambiguous reference, assuming memvar '_HMG_SYSDATA'
OwnButton.prg(96) Warning W0002 Ambiguous reference, assuming memvar '_HMG_SYSDATA'
Is it a problem?

It is not a problem.
These warnings occurs if you compile HMG program with parameter -w2 or -w3.
To avoid this, add in hmg.ch:

You can use RGB macro and GetRed, GetGreen, GetBlue functions:
Code: Select all
RGB(0xAA, 0xBB, 0xCC) --> 0xCCBBAA (dec: 13417386)
GetRed(0x00CCBBAA) --> 0xAA (dec: 170)
GetGreen(0x00CCBBAA) --> 0xBB (dec: 187)
GetBlue(0x00CCBBAA) --> 0xCC (dec: 204)
If your color is defined as 3 elemnts array
aRGB := {nR, nG, nB}
use
RGB(aRGB[1], aRGB[2], aRGB[3])
or
RGBfromArray(aRGB)
to obtain nRGB value.
Code: Select all
FUNCTION RGBfromArray(aRGB)
RETURN RGB(aRGB[1], aRGB[2], aRGB[3])

I did not know I could use RGB in Hexadecimal...
Thank you Krzysztof for your indications.

Hi Krzysztof,
I hope you do not mind, I made a small contribution based on your code.

Added cutomized colors and Gradient mode. I also fixed probably a typo in FrameColor of ODS_FOCUS in _OWNBUTTONDRAW C function. (I wrote Pablo FYG).
A big hug
