Changing display from canvas to form

[Danack]

During my game I want to change from rendering the game to display some text which I've done in a form.

How do I make sure that the screen has been cleared of all the game graphics ? If I was changing to another canvas I'd just call canvas.repaint but there doesn't seem to be a similar function for forms or lists ....

Hi,

it's just as simple as calling YOUR_DISPLAY.setCurrent(YOUR_FORM); and the VM renders the Form (or whichever Screen based displayable you are using) contents on the screen. With Canvas, only calling repaint() makes VM call the Canvas' paint() method and but with Screen based displayables you don't really need to worry with issues like that.

Kind regards,

Why don't you use the drawString method of the Graphics class?

Because it's quite a lot of text and I don't want to have to handroll my own scolling and formatting code.

Thanks Tinke - You're right, just setting the for to be current works.

I was being dumb and still calling the canvas.repaint() and canvas.serviceRepaints() which caused the corruption.

thanks

zivgr,

showing text on Canvas is out of the question if your Canvas activity is very time sensitive as drawString method is hideously slow.
