I need the help of some pros…
I tried to make a window semi-transparent on macOS and Windows (64 bit) using declares. Luckily, Xojo had a blog entry on exactly this topic: https://blog.xojo.com/2014/09/15/using-declares-in-your-multi-platform-desktop-apps/
While it works well when building my app as 32-bit app, it makes a completely invisible window on 64-bit apps and I have no idea why this happens.
Simple app: Just a button that contains an action event and this code from example:
Declare Sub setAlphaValue Lib "Cocoa" selector "setAlphaValue:" (windowRef As Integer, windowAlpha As Single)
setAlphaValue(Self.Handle, 0.5) //Here self refers to our Xojo Window instance
Any help is highly appreciated. Perhaps it’s time to update the blog entry for 64-bit systems…
