I am still hoping for the ability to set button face and text colors native to PB! You can set them on all OS now and though I am not an expert on Linux Gnome or Mac OS i suspect the calls may be similar enough!!!

Please Fred!!!

how you set then on windows?

last time I looked into that issue, it was literally impossible. Buttons do not show a facecolor property, no matter if you set it.

The button face color is not a solid color anymore unless you disable themes. The classic look is dying anyway, standard is skinned look for the majority. Also it's not colors anymore that are directly ploted to the device context, it's images. You would have to colorize them using e.g. the HSL color model. Since Vista this is directly possible by using DirectX/Direct2D but only for the native styles of Windows, not sure about custom skins. What finally kills this request is the cross platform aspect so I would say forget about it.

if you can do it in VB6 (and last time i looked though admittedly a few years ago...) you can!

from the API32

Windows provides default color values for buttons. The system sends a WM_CTLCOLORBTN message to a button's parent window before the button is drawn. This message contains a handle of the button's device context and a handle of the child window. The parent window can use these handles to change the button's text and background colors. The following table shows the default button-color values.

Value Element colored
COLOR_BTNFACE Button faces.
COLOR_BTNHIGHLIGHT Highlight area (the top and left edges) of a button.
COLOR_BTNSHADOW Shadow area (the bottom and right edges) of a button.
COLOR_BTNTEXT Regular (nongrayed) text in buttons.
COLOR_GRAYTEXT Disabled (gray) text in buttons. This color is set to 0 if the current display driver does not support a solid gray color.
COLOR_WINDOW Window backgrounds.
COLOR_WINDOWFRAME Window frames.
COLOR_WINDOWTEXT Text in windows.

An application can retrieve the default values for these colors by calling the GetSysColor function, or set the values by calling the SetSysColors function. For more information about system colors, see System Information. For more information about how colors are used with controls, see Controls.

Portability Issue The WM_CTLCOLOR message has been replaced by the set of control-color messages. When porting your Windows 3.x - based application to the Win32 API, you must modify any code that processes the WM_CTLCOLOR message.

I have used this to GET to button and text colors... just need to SET it

so I would use:

Code: Select all

BOOL WINAPI SetSysColors(

    int cElements,	// number of elements to change 
    CONST INT *lpaElements,	// address of array of elements 
    CONST COLORREF *lpaRgbValues 	// address of array of RGB values  
   );

like:

SetSysColors(COLOR_BTNFACE, #BUTTON, RGB(0,0,0))
SetSysColors(COLOR_BTNTEXT, #BUTTON, RGB(255,255,255))

wouldn't i???

{{{{{{{EDIT}}}}}}}
yep... y'all are right...

You can draw anything but what people wanted to tell is that there is no standard functionality for this so don't expect a compiler to make this possible.
Also the mention about themes is important, you can still draw yourself but does a user want to you to molest the appearance of a button?

To draw a button having the colors of desire use it in ownerdraw mode.

VB6 just owner-draws it. It doesn't use any special or secret API call to do it. In fact, a lot of things that VB6 does with a single command is just a lot of custom code behind it. That's what made VB6 so popular with beginner programmers. In contrast, PureBasic doesn't do all this hand-holding and is a real programming language like C.

(Edited to fix a typo).

True this!

a lot of things that VB6 does with a single command is just a lot of custom code behind it.

Well that explains the VB BLOAT!!!

OK I shall work out mine own system... just wish I knew where Gnozal has gone!

    StopDrawing() : ok=ButtonImageGadget(num,x,y,w,h,ImageID(img),flags)
  EndIf
  ProcedureReturn ok

btnWhite=ButtonColorGadget(#PB_Any,170,50,150,30,"white/black",#White,#Black)

Repeat : Until WaitWindowEvent()=#PB_Event_CloseWindow

I didn't come up with this code originally, so all credit goes to the original author, whoever he was. The original code is probably still here on the forums somewhere.

@UserOfPure

There is a problem with your code in that the appearance of the buttons degrades significantly when they are disabled.

Posted: **Mon Apr 12, 2010 11:07 am**

works very well for me !!

otherwise
this code works well too:)
but just for Windows

if you comment out the gadget 50 painted gadget 0.

Code: Select all

mywin= OpenWindow (0,0,0,218,68, "Coloured buttons" , #PB_Window_SystemMenu|#PB_Window_ScreenCentered )

  CloseGadgetList ()
  
  ; if comment change backcolor gadget = 0
  ContainerGadget (50,0,0,0,0 ) : CloseGadgetList ()
