6.27 MouseDown Event

Description:	Generated when a mouse button is depressed when the mouse pointer is over the control. The Click and DblClick events are generated after the MouseDown and MouseUp events. The control that receives the MouseDown event continues to receive MouseMove events until the corresponding MouseUp event - whether or not the mouse remains over the control.
ComboBox	Mouse events (e.g. Click, MouseDown etc.) are not generated when the Style property is "1 - DropDown" or "2 - DropDownList", and the drop down list is displayed.
DriveList	Mouse events (e.g. Click, MouseDown etc.) are not generated when the drop down list is displayed.
TreeView and ListView	Mouse events (e.g. Click, MouseDown etc.) are not generated when a label is being edited.

Form and GroupBox	1. VT_I2 - MouseButton S9(4) COMP-5 2. VT_I2 - ShiftState S9(4) COMP-5 3. VT_I4 - PosX S9(9) COMP-5 4. VT_I4 - PosY S9(9) COMP-5
Others	1. [VT_I4 - Index S9(9) COMP-5] 2. VT_I2 - MouseButton S9(4) COMP-5 3. VT_I2 - ShiftState S9(4) COMP-5 4. VT_I4 - PosX S9(9) COMP-5 5. VT_I4 - PosY S9(9) COMP-5
Description of parameters (with constants):
Form and GroupBox	MouseButton: Bit mask settings indicate the button(s) depressed. Numbering the bits 1 to 8, from least significant to most significant, the bit mapping is: 1 - Left button(POW-MOUSE-LBUTTON) 2 - Right button(POW-MOUSE-RBUTTON) 3 - Middle button(POW-MOUSE-MBUTTON) ShiftState: Bit mask settings indicate the state of each of the shift keys - Shift, Ctrl and ALT. Numbering the bits 1 to 8, from least significant to most significant, the bit mapping is: 1 - Shift key(POW-SHIFTSTATE-SHIFT) 2 - Ctrl key(POW-SHIFTSTATE-CTRL) 3 - Alt key(POW-SHIFTSTATE-ALT) For example if the parameter has a value of 5 (binary 00000101), this indicates that the Shift and Alt keys are depressed. PosX: The horizontal coordinate of the mouse position relative to the top left corner of the control. The ScaleMode property of the containing control determines the units. Pos Y: The vertical coordinate of the mouse position relative to the top left corner of the control. The ScaleMode property of the containing control determines the units.
Others	Index: When the control is part of an array, Index contains the control's index in the array. The descriptions of the other parameters (from 2 to 5) are the same as "Form and GroupBox".
