Calculating Label size depending on a string length [solved]

[mode7]

Hi guys,

I'm drawing a speech bubble on a gui. The text is put into a text label. I'm dynamically drawing the size of the textbox depending on the length of the string.

 int chars;
 int lines;

 while (text.Length >= chars) {
   
   lines++;
   chars = chars+26;
 }
 gbubble.Height = 13*lines;// 13 is the height of the font
 
The problem is that this is unreliable, sometimes I end up with spare lines and sometime a word gets cut off.
Has anyone an idea of a more precise way of doing that?

Theres a function that calculates the width of a string in pixels based on the font but i cant remember exactly what it is.. check the manual.

Do something like this:

Code: ags

int width = GetTextWidth(text, gbubble.Font); // is gbubble the GUI or the label? If it's not the label replace it here with the label's name
gbubble.Height = GetTextHeight(text, gbubble.Font, width);

Thanks monkey- that sounds good. I'll try it right away

Note that in the case of an outlined font you have to calculate the width of the outline font instead.
