is it possible to create some gadgets with transparent background?
I have tried with the command " setgadgetalpha gadget,128 " ( should have a transparency to 50%) but it doesn't work.

Besides the command " setpanelimage " the image is all opaque, are not there zones of transparency (all the zones should not be transparent instead where the pixel is equal to the color of the first pixel?)

Who can help me?
Thanks

The only gadget I've had any luck with making semi transparent is a window gadget. You can use it as a contain for the gadgets you want transparent maybe.
Here's some quick code

+ Code Snippet

global main
global Gadget1
global Gadget2

    `Make the main window into a gadget
    main=createGadgetFromWindow(mainWindow())
    `Create a window that can be made transparent to house the gadget
    Gadget1=createWindow(gadgetX(main)+50,gadgetY(main),75,20,"",-2147483648,0,0,main)
    Gadget2=createComboBox(0,0,75,25,Gadget1)
    addItem Gadget2,"Item1"
    addItem Gadget2,"Item2"
    setGadgetAlpha Gadget1, 128

do
	
loop

Now you should have a transparent comboBox on the title bar.

setGadgetAlpha only applies to window gadgets.

From the help files:

Quote: "
Sets the opacity of a window gadget. This can range from 0 (transparent) to 255 (opaque / solid).
This effect can add a nice graphical touch when used in moderation, but be aware of the potential performance hit on older PCs.
This command is only supported on Windows 2000 / XP.
"

setPanelImage requires a 256-color bitmap file for transparency to work.
