Checkbox and Radio are not transparent!?

[byte-one]

On Dialogs with clausula TRANSPARENT and gradient-background the text from this controls are not transparent! Any solution?

[Antonio Linares]

Günther,

Please review fwh\samples\TestTrn1.prg

Antonio, I am using not a bitmap as background!
I use as background:

Code: Select all  Expand view

...ON PAINT gradientfill(oDlg:hDC,0,0,oDlg:nHeight(),oDlg:nWidth(),{{1,CLR_WHITE,CLR_RED}})

Uwe, thats not transparent!?
And also the SAYS with clausula UPDATE are not transparent, when the text are updated!

Hello Günther,

All tests in Dialog and Folder :

Dialog and Folder with Gradient :
Folder is OK.

Then the transparent clause does not work

We have previously commented this issue on these forums. It is a Windows limitation:

Hello,

I did some tests with Dialog and Transparent :
The 2. Dialog captured the gradient from Dialog 1.
Checkbox and Radio are transparent.

Uwe, please show me the source!

Uwe,

I guess you are using a NULL brush, so there is no background brush and the one from the main dialog is seen

Antonio, is it possible to create a bmp from the gradientfill() function? The gradient colors for the background are from user and i will paint the dialog with this colors.

Antonio,
Another test. The Test-Dialog-gradient is complete different to the others.
The Dialog uses the normal Gradient-function as background.

Uwe,

Please run your tests in XP and see what you get

Or, are you using XP with a different theme ?

[Antonio Linares]

Günther,

You can use oDlg:SaveToBmp( cBmpFileName )

[ukoenig]

Antonio,

the tests i'have done with VISTA.

I tested with XP and Windows2000

Result :

XP : Radio and SAY is transparent. Checkbox not.

Windows2000 : only SAY is transparent.

Is there a solution for XP, maybe to get the checkbox working as well ?

I still have a question about the text :
For the new release of the tool, to create the background for windows and
Dialog, i added some new functions.
There is a preview for RADIO, CHECKBOX and SAY added.
As well, there is a new small dialog, to create a gradient
and then to cut and save the gradient as Bitmap to use as background ( with adjust ).
I have to test, what happens, using a bitmap ( not the gradient-function ).
Is it possible, to change the textcolor of RADIO, CHECKBOX and SAY at runtime ?



Regards
Uwe
