XmFrame: The Frame widget class

NAME

SYNOPSIS

#include <Xm/Frame.h>

DESCRIPTION

Frame is a very simple manager used to enclose a single work area child in a border drawn by Frame. It uses the Manager class resources for border drawing and performs geometry management so that its size always matches its child's outer size plus the Frame's margins and shadow thickness.

Frame is most often used to enclose other managers when the application developer wants the manager to have the same border appearance as the primitive widgets. Frame can also be used to enclose primitive widgets that do not support the same type of border drawing. This gives visual consistency when you develop applications using diverse widget sets. Constraint resources are used to designate a child as the Frame title, align its text, and control its vertical alignment in relation to Frame's top shadow. The title appears only at the top of the Frame.

If the Frame's parent is a Shell widget, the XmNshadowType resource defaults to XmSHADOW_OUT, and the Manager's XmNshadowThickness resource defaults to 1.

If the Frame's parent is not a Shell widget, the XmNshadowType resouce defaults to XmSHADOW_ETCHED_IN, and the Manager's XmNshadowThickness resource defaults to 2.

Classes

Frame inherits behavior and resources from the Core, Composite, Constraint, and XmManager classes.

The class pointer is xmFrameWidgetClass.

The class name is XmFrame.

New Resources

The following table defines a set of widget resources used by the programmer to specify data. The programmer can also set the resource values for the inherited classes to set attributes for this widget. To reference a resource by name or by class in a .Xdefaults file, remove the XmN or XmC prefix and use the remaining letters. To specify one of the defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the remaining letters (in either lowercase or uppercase, but include any underscores between words). The codes in the access column indicate if the given resource can be set at creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is not applicable (N/A).

XmNmarginWidth

Specifies the padding space on the left and right sides between Frame's child and Frame's shadow drawing.

XmNmarginHeight

Specifies the padding space on the top and bottom sides between Frame's child and Frame's shadow drawing. When a title is present, the top margin equals the value specified by this resource plus the distance (if any) that the title extends below the top shadow.

XmNshadowType

Describes the drawing style for Frame. This resource can have the following values:

XmSHADOW_IN

Draws Frame so that it appears inset. This means that the bottom shadow visuals and top shadow visuals are reversed.

XmSHADOW_OUT

Draws Frame so that it appears outset. This is the default if Frame's parent is a Shell widget.

XmSHADOW_ETCHED_IN

Draws Frame using a double line giving the effect of a line etched into the window. The thickness of the double line is equal to the value of XmNshadowThickness. This is the default when Frame's parent is not a Shell widget.

XmSHADOW_ETCHED_OUT

Draws Frame using a double line giving the effect of a line coming out of the window. The thickness of the double line is equal to the value of XmNshadowThickness.

XmNchildType

Refer to the XmNframeChildType resource description. The XmNchildType resource is obsoleted by XmNframeChildType, but is kept here for backward compatibility.

XmNchildHorizontalAlignment

Specifies the alignment of the title. This resource has the following values:

•

XmALIGNMENT_BEGINNING

•

XmALIGNMENT_CENTER

•

XmALIGNMENT_END

See the description of XmNalignment in the XmLabel reference page for an explanation of these values.

XmNchildHorizontalSpacing

Specifies the minimum distance between either edge of the title text and the inner edge of the Frame shadow. Clipping of the title text occurs in order to maintain this spacing. The default value is the margin width of the Frame.

XmNchildVerticalAlignment

Specifies the vertical alignment of the title text, or the title area in relation to the top shadow of the Frame.

XmALIGNMENT_BASELINE_BOTTOM

Causes the baseline of the title to align vertically with the top shadow of the Frame. In the case of a multi-line title, the baseline of the last line of text aligns vertically with the top shadow of the Frame.

XmALIGNMENT_BASELINE_TOP

Causes the baseline of the first line of the title to align vertically with the top shadow of the Frame.

XmALIGNMENT_CHILD_TOP

Causes the top edge of the title area to align vertically with the top shadow of the Frame.

XmALIGNMENT_CENTER

Causes the center of the title area to align vertically with the top shadow of the Frame.

XmALIGNMENT_CHILD_BOTTOM

Causes the bottom edge of the title area to align vertically with the top shadow of the Frame.

XmNframeChildType

Specifies whether a child is a title or work area. Frame supports a single title and/or work area child. The possible values are

•

XmFRAME_TITLE_CHILD

•

XmFRAME_WORKAREA_CHILD

•

XmFRAME_GENERIC_CHILD

The Frame geometry manager ignores any child of type XmFRAME_GENERIC_CHILD. This resource replaces XmNchildType.

Inherited Resources

Frame inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the reference page for that superclass.

Translations

XmFrame inherits translations from XmManager.
