 virtual int labelMouseDown(int _x, int _y, int _button, bool _Ctrl, bool _Shift);
public virtual int labelMouseDown (int _x, int _y, int _button, bool _Ctrl, bool _Shift);
abstract member labelMouseDown : int * int * int * bool * bool -> int
override this.labelMouseDown : int * int * int * bool * bool -> int
Public Overridable Function labelMouseDown (_x As Integer, _y As Integer, _button As Integer, _Ctrl As Boolean, _Shift As Boolean) As Integer

Remarks

Typically, when this method is overridden, the return value from a call to the super method is returned. This event is called only if a value is specified for the label of the control and the ShowLabel property of the control is set to Yes.

The following example shows how to display the parameters of a labelMouseDown event in the Infolog.

public int labelMouseDown(int x,  
                              int y,  
                              int button, 
                              boolean Ctrl, 
                              boolean Shift) 
{ 
    int ret; 
    if (Shift) 
    { 
        info( "Shift set" ); 
    } 
    if (Ctrl) 
    { 
        info( "Ctrl set"); 
    } 
    info (strfmt("x, y: %1 %2 button: %3", x, y, button)); 
    ret = super(x, y, button, Ctrl, Shift); 
    info (strfmt("ret: %1", ret)); 
    return ret; 
}
