GradientFill()

[Bayron]

Code: Select all  Expand view

GradientFill( hDC, 0, 0, oDlg:nHeight, oDlg:nWidth, ;
                                   { { 0.5, 8388608,16117445 }, { 0.5, 16117445, 8388608 } }, .T. )
 

The anterior code, fills a Dialog from Top to Bottom and Bottom to top with a Gradient...(Sample by Daniel)

Is there a way to do it Top to Bottom, Bottom to top, Left to Right and Right to Left simultaneously???

Hello Bayron,

True and False defines the Direction.

GradientFill( hDC, 0, 0, oDlg:nHeight, oDlg:nWidth, ;
{ { 0.5, 8388608,16117445 }, { 0.5, 16117445, 8388608 } }, .T. )

GradientFill( hDC, 0, 0, oDlg:nHeight, oDlg:nWidth, ;
{ { 0.5, 8388608,16117445 }, { 0.5, 16117445, 8388608 } }, .F. )

You can test all Settings with the Tool :



I just noticed, the darkblue-area ( Bottom and Right ) is different using the same Values.
Maybe the Vertical Dialog-Height must be adjusted like oDlg:nHeight-20 because of Dialog-Title,
to get the same Gradient-effect.
The Screenshot shows a Test on the Main-window. I will check both Window and Dialog.

Best Regards
Uwe

Uwe, Thanks for the answer, I am aware of the clause .T. or .F., but what I want is a gradient from both directions simultaneously. I know we have a CircleGradient(), I will like kind of a SquareGradient()

Hello Bayron,

there are different Styles and Effects of Square Gradients.
Paint a Gradient-Square of Your Taste and save it as a JPG.

Just a sample :



For a Test, save these Images to Your \Bitmap - Directory
and Select them as Dialog-Image-Background

That is exactly what I want, but I need to do that programaticly, because I want to get rid of external bitmaps or resources...
