No, it is not what I need.
I need the background of imagesprite is fixed with this image even if I click on the imagesprite.
When I need to hide top and bottom for icons I click on the page like this.
Is it possible to add one more button to show a button and a TextBox on the center of canvas when I click the show button and the TextBox canvas_revised_Show_Button.aia (76.0 KB)
Yes. Using the extension again, set a vertical arrangement, fill parent both ways, centred both ways, and place a button in it. Then use the same logic with visibility to hide and show it as required.
