B4J Question Set rounded corner for rectangle

bdunkleysmith · Apr 1, 2016

I set the color of several rectangles in a particular application by using code like:

B4X:

Dim joRect As JavaObject = RinTeamFoulsRect
joRect.RunMethod("setFill", Array(fx.Colors.Red))

Now I want to make the rectangle have rounded corners and so tried:

B4X:

Dim joRect As JavaObject = GameClockRect   
joRect.RunMethod("setArcHeight", 30)
joRect.RunMethod("setArcWidth", 30)

but syntax I've used for the arc parameters is throwing errors.

Can someone please suggest the correct syntax?

Thanks,

Bryon

If it was a regular control then you could have used CSSUtils.SetBorder to set rounded corners.

This code will work:

B4X:

Dim d As Double = 30 'must use double variable
joRect.RunMethod("setArcHeight", Array(d))
joRect.RunMethod("setArcWidth", Array(d))

Thanks Erel, your tech support is amazing!

Incidentally this application consumes data from an Arduino board and so I'm looking out for B4R with interest.
