Tool_Tag::Height

Return the vertical dimension (in pixels) of the tool.

Syntax

int Height(

unsigned short nb=4

) ;

Parameters

the number of rows of TAGs visible in the tool. Each row has 4 TAG buttons, if there are more TAGs available than what can be displayed, then a vertical slider will be enabled to scroll the list. If no argument is provided, the tool will display 4 rows of TAGs

Return value

The vertical dimension of the tool (in pixels).

Remarks

This method is usually called in Ctrl_Register() to reserve the space for the tool and then again in Ctrl_Resize() to position the tool.
