_FillGradientTriangleRect()

Hi!

Stumpled across a quite interesting function on msdn today and decided to make a little UDF of it muttley

It fills a gradient triangle or a rect on a device context.

Here's the msdn link: msdn

This is how it looks:

Pretty sweet eh?

Here's the UDF and the above example:

I found some parts of the function quite confusing so the function is not anywhere near perfect, but hey! It works :)

Happy Coding!

It's great monoceres.

It needs some way to set the number of vertices in the dll call. If you change your example to have

_FillGradientTriangleRect($dc,$array,$GRADIENT_FILL_RECT_V)

then it draws 2 rectangles.

Thanks everyone for your comments, really appreciate it :)

Maybe you should rename it to something like:

_GUIPlus_FillGradTriangle()

And see if it can be added to: _GUIPlus.au3

Good job!

It's GDIPlus :dance:

And yeah, maybe if I make this more structured I try to get it included.

Nice one monoceres!

Of course not, I didn't handle the WM_PAINT message :cheer:

Easy enough to add:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

;....
GUIRegisterMsg($WM_PAINT,"_ReDraw")

;....
Func _ReDraw()
    _GDIPlus_GraphicsClear($graphics, 0xFF000000)
    _FillGradientTriangleRect($dc, $array, $GRADIENT_FILL_TRIANGLE)
    Return $GUI_RUNDEFMSG
EndFunc

I think it's because I was lazy and always passed a GRADIENT_TRIANGLE structure to the dll. muttley

Fixing it later :P

Well that will draw a triangle which is not so good if you want to redraw a rectangle, and if you've changed to array to get ready for a later draw then it would be even worse. Maybe there should be something in the function _FillGradientTriangleRect to set some global varaibles with the parameters, and have the redraw function use those.

Func _ReDraw()
    _GDIPlus_GraphicsClear($graphics, 0xFF000000)
    _FillGradientTriangleRect($lastdc, $lastarray, $LAST_GRADIENT_TYPE)
    Return $GUI_RUNDEFMSG
EndFunc

You're right, but I will not implement any redrawing into the UDF, because I think it's up to the user to redraw the contents of his device.

I for one would not want a UDF to draw anything into my device when I don't call the function directly.

Yes, I agree with you.

Thanks.

There's a typo/error. GUI appears on about line 7.
