Transpernet Region

[hfheatherfox07]

Still on the Areo skin project I realized that the middle of the window should be opaque .... Here: http://www.masm32.com/board/index.php?action=dlattach;topic=18686.0;id=10651
basically I do not want the whole window transparent ...
I used CreateRectRgn and CombineRgn ..they work .... but the whole window becomes transparent why?

I commented out "INVOKE SetWindowRgn,hWnd,hr,1" other wise It cuts a hole but the purpose of that there was to test whether the regions are being created
"INVOKE SetWindowRgn,hWnd,hr0,1"  reverses the region desired ....

I have used the handle of that region to invoke the transparent proc "invoke TranspWindow,hr0,TRANSPARENT_VALUE"
but still no go .....

why?  ::)

Also I included 3 ways to do a transparent widow

that should be easy to fix
use a different color, like violet, for the pixels that you do want to be transparent
(or some other color that isn't used elsewhere in the image)

i think GdiTransparentBlt is the function to use   :U

I tried that with a bunch of colors and that did not work for me ..... Do you mean I am going to that color on the window?  cause I want to have that the same color

[hfheatherfox07]

but why doesn't the reverse region work?

[dedndave]

here is an example using TransparentBlt
use GdiTransparentBlt, instead
same function - but you do not have to include msimg32.inc and includelib msimg32.lib

As usual, you supplie N examples, thus people must guess which one shows the problem...

[hfheatherfox07]

I am confused I just want to make one part of my window not transparent but I do not want it violet LOL ....
I prefer to get my way going some how with create region and subtract that form the main widow and only make that main widow transparent

[dedndave]

if it's transparent, the violet won't show   :bg
don't make me use the homer icon twice in one day - lol

maybe you want to create a mask and do it that way
the thread i posted also has an example for that

[qWord]

not sure if this is the code you are using, but is has the problem, that the coordinates a not proper maped to screen coordinates

Code Select Expand

invoke CreateRectRgn,40,60,170,155  ; <= client coord.
mov hr0,eax
invoke GetWindowRect,hWnd,addr rc
mov eax,rc.right
mov ecx,rc.bottom
sub eax,rc.left
sub ecx,rc.top
invoke CreateRectRgn,0,0,eax,ecx   ; <== (0|0) = left top corner of the screen
mov hr,eax
invoke CombineRgn,hr,hr,hr0,RGN_XOR

Wops .... how do I fix that?  the one is the smaller region with in the window

[qWord]

The magic functions are ClientToScreen() and ScreenToClient()  :U

[hfheatherfox07]

The magic functions are ClientToScreen() and ScreenToClient()  :U

I don't understand that.......

but good catch on the  invoke GetWindowRect,hWnd,addr rc ...
that is why I am getting left top corner of the screen
Could I just use invoke GetClientRect,hWnd,addr rc
that should return the Client rect in my window ..right ?

[hfheatherfox07]

The magic functions are ClientToScreen() and ScreenToClient()  :U

by the way I searched those words and came up with this http://www.masm32.com/board/index.php?topic=17383.0

Love your example there NICE!  :U

I was looking for something like that way back

[dedndave]

here's one i am working on...
BaldurIIMap.zip

when i started working on it, qWord's example you linked was one of the programs i looked at   :P

[hfheatherfox07]

That is from the multiwin example ( that format of win in win)
