Hi,

I don't know if this can help you...
Text areas have a "transparent" parameter.

[super_li]

thank you very much,
I had set "transparent" parameter to true ,and sent Text areas to front,

also the white color bitmap sent to back in this custom dialog box.

but it is still non-transparent

Can anyone help me?:( 😞 😞
