  • 项目

Returns the row position of the mouse pointer in the main Visual FoxPro window or in a user-defined window.

MROW([cWindowName [, nScaleMode]])

Return Values

Numeric

Parameters

  • cWindowName
    Specifies the name of a window whose mouse-pointer row position MROW( ) returns.
  • nScaleMode
    Specifies the unit of measurement for the value MROW( ) returns. The settings for nScaleMode are:
    nScaleMode Description
    0 (Default) Foxels. A foxel is equivalent to the average height and width of a character based on the current font of the form in which an object is contained. Foxels are useful in developing cross-platform applications for character-based and graphical platforms.
    3 Pixels. A pixel is the smallest element that can be displayed on a screen or printer. Pixels are screen-dependent.

Remarks

MROW( ) returns the main Visual FoxPro window row position of the mouse pointer if there is no active user-defined window and you omit the optional argument.

MROW( ) returns the mouse-pointer row coordinate relative to the active user-defined window if there is an active user-defined window and you omit the optional argument. MROW( ) returns a value of –1 if the mouse pointer is positioned outside the user-defined window or if no mouse driver is loaded and there is no output window.

Using the MROW( ) function without an optional argument may affect the behavior of code on forms with the AllowOutput property set to False (.F.). For example, the placement of a shortcut menu that is defined in the RightClick event, may not be displayed in the proper location, if you use the MROW( ) function to determine where the menu is displayed.
