B4J Question Label - set height to max based on content

[mfstuart]

How do you set the height of a Label node, in code, to the height (width is set and cannot change) that will show all content of the label?
I've tried setting the Label.Height and Label.PrefHeight to no avail.

I'm trying to use this with the JFXPrint8 library.

Thanx,
Mark Stuart

Start by setting Private xui as XUI in Process_Globals (add XUI as library)
With B4XView you have much better control of the dimensions of a label.
With B4Xcanvas you can get the exact height of text.

Typically:

    Dim cv As B4XCanvas  'ignore, this doesn't need to be initialized for this purpose
    Dim alablx As B4XView = alabl                    'alabl created with designer or in code'
    alablx.Text = "XXXX"
    alablx.Height = 2 * cv.MeasureText(alablx.Text, alablx.font).Height
