How do I shadow the text in the following example


Recommended Posts

Given the code fragment below (assume all the pre-requisites are in-place), how do I shadow the text in the label?

I have searched and done some experimenting but I can't seem to get what I want, the text "Button" shadowed.

The code fragment is:

GUISetFont(16, 800, 0, "Arial")
$cLabel3 = GUICtrlCreateLabel("Button", 200, 140, 220, 50)
GUICtrlSetBkColor($cLabel3, $GUI_BKCOLOR_TRANSPARENT)

Regards,

Jim

Thank you.

Unfortunately this is one of several similar approaches I have experimented with and, like you, I do get a shadow. However, the one of the issues I am having is with the following line:

$hFont = _WinAPI_CreateFont(65, 0, 0, 0, $FW_NORMAL, 0, 0, 0, $DEFAULT_CHARSET, $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $ANTIALIASED_QUALITY, BitOR($DEFAULT_PITCH, $FF_DONTCARE), 'Arial')

This is a "skinning" application and the only font size information I have is what the font is to be , eg., "Arial size 16" like the GUISetFont shows, but the illustrated line requires a font height and I can't find a way to get from one to the other other than a WAG.

I also encountered another issue with the text color in the "_WinAPI_DrawShadowText" call. If I specify total black 0x00000000, I get no shadow. However, if I specify 0x00000001, I get "black" and the requested shadow.

But I can live with that by simply changing any black text color request to 0x00000001.

However, the font size is a problem.

Again thanks.

Regards,

Jim
