Tool_Histo::Height

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

Syntax

int Height(

unsigned short nb=100

) ;

Parameters

the desired height of the tool. This is exactly the value that the method will return. In other word, this method return what you gave it. It only exist for the sake of completion since all the other classes have a "Height" method. If no argument is provide, the default is 100 pixels.

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.
