B4J Question [Solved] Select/change screen when using multiple monitors

[pierrem]

Hi,

jfx.screens returns a List with all the screens. Each element in the list is a Screen object

How to select one of the returned screen object and/or show on form on it


thanks

You need to get the target screen coordinates and then set the form position with Form.WindowLeft and WindowTop.

Concise and effective, as usual

Thanks Erel

FYI ....

When the secondary monitor is located at the left of primary monitor,
secondary.minX is negative

In my case,
Secondary.maxX & maxY seem to be wrong ...
the 2 values are : 3072 x 1068

the monitor is almost 4K, windows10 gives 3840 x 2160 ....

I can resize if to fully fill the whole screen .....
