SetEllipsize for Multiple Lines in B4X Labels
In B4X, the default behavior for ellipsizing text in a Label is limited to a single line when the SingleLine property is set to true. This often restricts developers who want to display longer text while still managing how it is presented in the UI. The SetEllipsize Sub provides a solution by allowing you to set ellipsizing for multiple lines (e.g., two lines) without needing to enable the SingleLine property. This enables better control over text display in Labels and improves the user interface by ensuring that overflowing text is handled gracefully.

Get Actionbar Height
I needed a way for users to access the OS network settings in a âclosedâ HMI without being able to access other menus. Therefore I had to cover the actionbar with an own overlay. To find out the height to use, I developed the following function. I have not tested whether it works with a non-rooted and other devices.

setError[] - the forgotten pop-up
Sets the right-hand compound drawable of the TextView (google-ese for our label view) to the "error" icon and sets an error message that will be displayed in a popup when the TextView has focus.
