I need Help with seekbar

MonteliaRO · July 14, 2020, 1:21pm

Hello, I have a question. I wanted to know if I could make another window in the pop-up menu ("⋮") and because the text size can be set with a seekbar (slider) can someone help me?

@MonteliaRO ===
it s difficult to help you without undersatanding exactly what you mean… Can you explain better “make another window” and for which text do you want a slider for “text size”…

You mean another item of the pop-up menu showing a seekbar?
Here you have such a code. You have to give the values of the seekbar, like width, x and y value etc. in the onStart () function. Do not make a variable for them in setup. You can change them afterwards with a runable. As you can see; each time you make the seekbar visible/ unvisible you also need a runable.
