METAFILE

A METAFILE control merely displays an METAFILE image (ie, some graphic stored in a meta file format).


Uses

Can be used for decoration or display some visual information such as a picture.


Styles

A METAFILE may have any, all, or none of the following styles:

NOTIFY Causes the Window Layout's DBLCLK or CLICK subroutines for this control to be called when the mouse is double-clicked or clicked on the image.
SUNKEN Creates a border with a sunken edge around the picture.
FILL If the image is smaller than the METAFILE area, the rest of the area is filled with the color of the pixel in the top left corner of the image.
FIXRIGHT The lower right corner of the METAFILE is to remain fixed when the control is resized. Only the top and left sides are adjusted to accommodate a new image loaded into the area.
FIXSIZE The METAFILE (area) is not resized to fit the real size of the image. If the image is larger than the METAFILE area, the image is clipped to fit the original METAFILE area.
NOSIBLING Prevents this control from drawing into any overlapping controls.
GROUP Marks this control as the first of a group of controls in which the user can move from one control to the next with the arrow keys. All subsequent controls (after this first control) belong to the same group up to the next control that has its GROUP flag set. (ie, One group ends where the next begins).
DISABLED Control is initially disabled. You can later enable it with a call to GuiSetCtlPlacement.
HIDE Control is hidden. You can later make it visible with a call to GuiSetCtlPlacement.
BORDER Creates a border around the picture.


Extra styles

A METAFILE can have the following extra styles:

MODALFRAME Has a double border.
STATICEDGE Has a three-dimensional border intended to be used for controls that do not accept user input.
CLIENTEDGE Has a 3D look comprised of a border with a sunken edge.
FILES Accepts drag-and-drop files (ie, the DROPFILES event).
TRANSPARENT The control is to be transparent. Any controls that are beneath this one are not obscured.


Events

A METAFILE generates the following events:

Event name When it occurs
CLICK The user has clicked on the image. Note: A disabled METAFILE does not cause a CLICK event. This event also does not occur if the NOTIFY style is not specified for the control.
DBLCLK The user has double-clicked on the image. Note: A disabled METAFILE does not cause a DBLCLK event. This event also does not occur if the NOTIFY style is not specified for the control.


REXX Variable

A METAFILE must have a REXX variable associated with it only if you specify the NOTIFY style, or you wish to be able to change its state (with GuiSetCtlPlacement) or image. You do not need to initialize the variable before opening the window which contains the METAFILE control.
