Changing a control's color !

[Gilmar de Paula Fiocca]

Richard,

I was using GRAPHIC windows, but in some machines they are REALLY slow, the drawing of "natural" Windows dialogs are much faster. I think it is because Directx... Who knows...

Sorry, I didn't mean to be rude, just thought you didn't know that in PBCC you could use dialogs !

Thanks for helping.

Richard, I'm using console compiler, but I needed an Dialog ! Yes you can use dialogs in PBCC !!! The problem is that you have to deal with Windows API !

Yes, you can ... but I was trying to make sure that is what you were really trying to do. For that matter you can do a "dialog", depending on what is in it, with PB's GRAPHICS in a subclassed GW. Many examples since 8.0 was released years ago. and with 9.0 much easier.

Thank you Michael, but using this way the control's background is set to "WHITE", using a created brush solved my problem.

Good morning,

Richard, I'm using console compiler, but I needed an Dialog ! Yes you can use dialogs in PBCC !!! The problem is that you have to deal with Windows API !

It worked ok, with some minors adaptations in Jerry's code, because I had the dialog created in a resource file, not by code.
After all, the only thing I had to do is create the brush to use in the callback.

Thanks for your help Jerry and Kev !

FUNCTION = GetStockObject(%WHITE_PEN)

This is wrong, you can only return a HBRUSH (brush handle) from the WM_CTLCOLORXX functions. If you need a fixed, non-system color, then create the brush with CreateSolidBrush() in somewhere like WM_INITDIALOG and save the handle in a STATIC variable, then you can return this handle in WM_CTLCOLORSTATIC. The brush can be deleted in WM_DESTROY or wherever you are done with it.

If you need to use a system color, it's very simple: just use GetSysColorBrush().

I don't know if this is what you are looking for, but here's an example generated by Jaxgui that should work in PBCC.

Which PBCC compiler version are you using? IOW Doesn't this post belong in the PBWin or Programming forum?

Hi,

Anyone could help me ?
I created a dialog using ResEdit/RC. I've managed to change the text and font of the created static controls in it, ie. labels, but I'm having difficulties
in changing the color of them.
I know that I have to use the API functions "SetBkColor" and "SetTextColor", but I do not know how to use them.

LOCAL hFont AS LONG ' Handle for font
LOCAL hControl AS LONG ' Handle for control
LOCAL hWnd AS LONG ' Handle for window
LOCAL hDC AS DWORD ' Handle for device context
LOCAL szText AS ASCIIZ * 50

.
.
.

' Changing font... Works fine !
hFont = PBFormsMakeFont("Courier", 9, %FW_EXTRABOLD, %FALSE, %FALSE, %FALSE, %DEFAULT_CHARSET)    		
SendMessage hControl, %WM_SETFONT, hFont, 0&

' Changing caption... Works fine !
szText = "Test"
SetWindowText(hControl, szText)

' What I'm trying... Didn't work completely right !...
' This is the code of my callback procedure
SELECT CASE wMsg
    CASE %WM_CTLCOLORSTATIC
  	SELECT CASE GetDlgCtrlId(lParam)
  	    CASE %IDC_VISOR5
      		SetBkColor wParam, %RED
      		SetTextColor wParam, %WHITE
      		SetBkMode wParam, %OPAQUE
                                                   
                          ' The objective is to change the background in the hole control to RED ! Now I'm getting only the text to the colors I needed. Not the hole background !
                          ' Don't know which object to use ! Tried BLACK_PEN, BLACK_BRUSH, DC_BRUSH, DC_PEN, neither one worked as I expected.
      		FUNCTION = GetStockObject(%WHITE_PEN) 
      		EXIT FUNCTION
      	END SELECT

.
.
.

Anyone could point me in the right direction ?
Thanks !
