drawlabel issue, old text remains in label

[Nemena]

Hi all, I bought mikrommb board with visual tft and I'm stuck at the beginning.
I try to change the caption of a label, but the old text stays under the new one. If I change the caption of a button, the old one disappears. Any help is appriciated.
project is attached:
Best Regards:

Hello, Nemena

Text is not updated as you type, but on ENTER press, or when you click on another property in Object Inspector.

Hello nlukic,

I'm not talking about the editor window.
IF you open the project, you see there is a button on the screen and 4 labels.
On click event the caption of the button and the labels should change.
The caption of the button changes fine, but the old text of the label remains below the new text on the mikrommb 18fj board.

Has anybody tried my project?

Hello,

You can not erase label (or other object) by simple calling draw function. You need do erase old text manually. The simplest way to do this is to add a box behind a labels, and each time you want to draw labels, first call DrawBox(Box1), than DrawLabels...
I'm sending you yours changed example in attachment.

That is a bit complicated isn't it?
How come the caption of a button can be changed without this procedure and the caption of a label not?

[nlukic]

There is conceptual difference between button and label object and the way it is draw. You always know what is behind text that placed on button, so you can redraw it as well, but you can not know what is behind label so you can not erase all behind it like that. But, we can put a property in Label object, called for example, transparent so you can turn it on and off.

The attached project does not work for me on mikrommb board. I get the same numbers for x_max and y_min.
Could someone tell me why??
I've spent a lot of time trying.
thank you!
