Rectangle Not Transparent?

???

Sub TextChange() Handles TextChange
  Me.SelectionStart = 0
  me.SelectionLength = 1
End Sub

Will cause wild behaviour when typing of course ā€“ but always highlights the first character when placed in a TextArea.TextChange Event Handler.

How about selecting just the text? No need for styled text run

As you can see there is a timer and as i type the characters vanishes. Just like any typing test software
to check Words Per Minute.

Just now need to find a way to change the selection color. :100:

Read the catch on the bottom:

When used in an unstyled TextArea , it changes the color of all the text in the TextArea .

If your problem is about a Windows program, you should move this conversation to the Windows channel (in Platforms).

Under recent versions of Xojo, true transparency is not available. Only pseudo transparency, which means the control takes the color of the parent.

I am not sure you can change the selection color.

Another way to do what you describe would simply be to draw the text into a canvas, where you will have more control, and be able to draw the colored rectangle, just before drawing the string.

Of course, this means the text would be static in the canvas.
