Visible and invisible

i want invisible the button.
Plz help me.

Try Button width = 0, height = 0 (gone) or set the background and label color to transparent (hide).

and image ???

To hide the image, set the picture property = empty string

Put the button inside a row or a column and set it to height to 0% when you want to show it again set the row or the column to the size you want or to “Fit contents”

Could be so. It is a pity that Slider, Switch and Label can not be hidden in the same way.
