FontColor and button - is it possible to change?

[KDJ]

PD: A suggestion: should be used to draw the button the api functions that draw with the style of Windows active theme, otherwise the button is flat and the other controls are drawn by superimposing layers of images that recreate the active theme. 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.

Below is the new version of owner draw buttons.
Added: gradiend for backgroud color.
Warning: changed aColor structure. I'm sorry for the inconvenience.

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:

Code: Select all

MEMVAR _HMG_SYSDATA

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).
