  • Erase text without clearing the whole screen


    I would have a few more questions for you. To recap my situation, I am using a PIXXILCD-25P4-CTP with Workshop 4 Pro.

    What I want to do is : when I slide to the top of my screen, I want the text "Drag and drop" to appear and 1 second later, I want the text to disappear and the slider to go back to his initial position.

    To make the text disappear, I used gfx_Cls() but it makes all my others graphics disappear, and I don't want this of course. I can't find the solution to clean the text and the slider. Maybe you know a solution?

    Thank you !

    You can draw clear text by drawing the background color in the region where you printed text.

    You can use the function gfx_RectangleFilled(x1, y1, x2, y2, colour)

    I hope this helps.

    Best Regards
