Dynamic size of label/checkbox control

[sugi]

Hello,

I need to figure out how to calculate the width that a checkbox needs to have to show the full text. At the same time, wasting space by oversizing them is not an option, because I have to place an input field right next to it.

Basically the GUI I have to create looks like the following (with a non-fixed-width font):

[ ] Point 1 _____________________

[ ] Point 1.1 ___________________

[ ] Point 1.2 ___________________

[ ] Point 2 _____________________

Where the underscores stand for the input box. If I know how big the checkboxes are, I can size the input box automatically.

How can I calculate how I have to size the checkboxes?

Thanks!

_MeasureString() function

Thank you smashly, that seems to be exactly what I was looking for!

$string_checkbox1 = "Teststring a"
$string_checkbox2 = "Teststring bbbbbbb"
$string_checkbox3 = "Teststring c"
$checkbox1 = GUICtrlCreateCheckbox($string_checkbox1,10,20,stringlen($string_checkbox1)*6.5,20)
$checkbox2 = GUICtrlCreateCheckbox($string_checkbox2,10,40,stringlen($string_checkbox2)*6.5,20)
$checkbox3 = GUICtrlCreateCheckbox($string_checkbox3,10,60,stringlen($string_checkbox3)*6.5,20)
GUICtrlCreateInput("",10+stringlen($string_checkbox1)*6.5,20,180-stringlen($string_checkbox1)*6.5,20)
GUICtrlCreateInput("",10+stringlen($string_checkbox2)*6.5,40,180-stringlen($string_checkbox2)*6.5,20)
GUICtrlCreateInput("",10+stringlen($string_checkbox3)*6.5,60,180-stringlen($string_checkbox3)*6.5,20)oÝ÷ Ûú®¢×©ä°ú%Ê^»­¶½êÚì"vØh}§!j¸¬^ «y:ò¶¬zËkx,jëh×6$string_checkbox1 = "Teststring IIIIIII"

Edit: looks like the quick edit function does have a problem with me
