TrackMouseDown

void CATControl::TrackMouseDown ( const CATPOINT &  point, CATMODKEY  modKey   ) [virtual] TrackMouseDown() is called when a button is pressed inside the control. Generally, this should toggle the control into a pressed state, but not register a click or anything yet until TrackMouseRelease() is released within the same control. After TrackMouseDown() is called, the control will begin receiving TrackMouseMove() calls if the mouse pointer is moved. Parameters: point  - location the mouse was pressed modKey  - Key state modifiers for ctrl/shift/alt/etc. Reimplemented in CATKnob, and CATSlider. Definition at line 788 of file CATControl.cpp. References fActive, fPressed, and CATWidget::MarkDirty().
