View list of data type meanings


This calculates how many pixels a particular piece of text will take up, which can help in calculating how big a window to create, or where to put other things. Note that WindowText returns the number of pixels when it draws text, so you don't need to call WindowTextWidth simply to work out where to draw the very next item.

WindowName - the name of an existing miniwindow.

FontId - a font id that you have loaded.

Text - the text to be calculated (maximum of 8192 characters)

Unicode - if true, the text is Unicode text in UTF-8 format

For more information, see:


Note: Available in version 4.34 onwards.

Lua example
width   = WindowTextWidth (win, "f", "Lazy dog yawns")  -- width of text
Returns If successful, returns the number of pixels the text would take horizontally.

If unsuccessful, returns a negative number as follows:

-1 : That window name does not exist
-2 : That font was not loaded
-3 : For Unicode, invalid UTF-8 sequence
Introduced in version 4.34
