Erase string

Hello Rashmi,

To erase it please print NULL characters to the string.

E.g. if the string sent initially is "ABCD" then next time to erase it use " "

Hi Amit,

I tried your method of printing NULL characters, but it doesn't work. It works with push buttons but not with GrStringDraw

Hello Rashmi,

Can you please paste the code line that you are using to Erase?

Hi Amit,Say the original statement is
GrStringDraw(pContext, "ZO Cartridge Last Recharge #4 ", 150,
10, 75, 0);
If I want to overwrite this , then I write the below statement
GrStringDraw(pContext, " ", 150, 10, 75, 0);

Hello Rashmi

Turn the position Opaque (the last parameter).

GrStringDraw(pContext, " ", 150, 10, 75, 1);

Hi Amit,

That doesnt seem to make any difference. The background colour of screen is Light Grey and not default black.

Hello Rashmi

That is the only way to erase the string. Or you may have to create a text box and then access the pixel to change the color (either using the text box or by accessing the low level drivers).
