Say Transparent...problems - ( Gradient Partial )

[Ale SB]

In recent versions, there are problems of Transparency, using the Function GradientFill(...).

There is another type of solution?

We would like to continue using Gradient partial screen!!!

TRANSPARENT Controls on Multiple Gradient
I will create a little tool, adding some Sliders to test/define color/gradient-positions
as well there will be 4 Color-selectors and Text color-selection ( VISUAL DESIGN )

It looks better, using the same connection-color :



Your color-selection :



2 Gradients and 1 Color :

Ukoenig;
is a good idea!
Can you show me your code Gradient?

I'm doing some testing with FixSays (...), ultilizando in class tdialog ...

FixSays (:: hWnd, GetStockObject (NULL_BRUSH)) works, but if I take a refresh at Say he loses transparency.

But thanks for the tip.

Can we not simplify this program using the latest features like GRADIENT clause?
Also we can derive one combined aGrad array from multiple Grad arrays.

Code: Select all  Expand view

function TestGradPartial()

   local oDlg, oFont, oBrush
   local aGrad

   aGrad := { { 0.10, RGB( 219, 230, 244 ), RGB( 207, 221, 239 ) }, ;
              { 0.10, RGB( 201, 217, 237 ), RGB( 231, 242, 255 ) }, ;
              { 0.51, RGB( 255, 255,  25 ), RGB( 255, 255,  25 ) }, ;
              { 0.29, RGB( 100, 200, 100 ), RGB( 255, 230, 200 ) }  }

   DEFINE FONT oFont NAME "Arial" SIZE 0,-12 BOLD ITALIC
   DEFINE DIALOG oDlg TITLE "Test Gradient Partial" ;
      FROM 0,0 TO 307,286 PIXEL ;
      COLOR CLR_BLACK, RGB( 255, 255, 25 ) ;
      FONT oFont GRADIENT aGrad TRANSPARENT

   @  08, 04 SAY "GRADIENT PARTIAL TOP - GradientFill(...)" OF oDlg SIZE 145, 10 PIXEL
   @  70, 04 SAY FWVERSION OF oDlg SIZE 145, 10 PIXEL
   @  82, 04 SAY "oDlg:SetColor( , nRGB( 255, 255, 25 ) )" OF oDlg SIZE 145, 10 PIXEL
   @ 130, 04 SAY "GRADIENT PARTIAL BOTTOM - GradientFill(...)" OF oDlg SIZE 145, 10 PIXEL

   ACTIVATE DIALOG oDlg
   RELEASE FONT  oFont

Mr. Rao,
it works, but with some restrictions :
a style-combination ( horizontal / vertical ) is not possible
also to define the position of the colors inside a gradient ( 0 - 1 ).

The first results of the painter.
It saves much work, because You can create a Dialog in DESIGN-MODE.



Create the needed Gradients and define the Textcolors



Define Dialog-size and Gradient-sections
for the section-define, Splitters are used



Display the Design-result with selected Sections, Gradient and Dialog-size:
You can MOVE the Controls, to test the Textcolors with the Gradients.
The selected Control-positions together with the other defines are saved to a DBF.



Best Regards
Uwe

Hello,

With the new Release it will be possible,
to split in DESIGN-mode a dialog in 3 sections with any brush-combination :

Resize in DESIGN-mode



Select any combination of sections
