XmIconGadget: The IconGadget widget class
NAME
XmIconGadget --- The IconGadget widget classSYNOPSIS
#include <Xm/IconG.h>
DESCRIPTION
IconGadget is an instantiable widget used to display both text and a pixmap in various combinations. Other widgets that hold the XmQTcontainer trait, such as Container, can use IconGadget to represent objects.
IconGadget text is a compound string. If no text is supplied, then the compound string is generated from the gadget name. IconGadget text is placed relative to the type of associated pixmap.
Depending upon the XmNviewType resource, IconGadget can display two views:
- XmLARGE_ICON
- The IconGadget text string is displayed below the pixmap, and centered.
- XmSMALL_ICON
- The IconGadget text string is placed on the side of the small icon, in the widget's XmNlayoutDirection.
A bitmap mask can be supplied for each pixmap to clip the pixmap into some shape other than a rectangle. The XmNlargeIconMask and XmNsmallIconMask resources specify the large and small bitmap masks respectively. Visual emphasis for the IconGadget is provided with the XmNvisualEmphasis resource. IconGadget's XmNdetail and XmNdetailCount resources provide a detail view for IconGadgets, enabling the display of Strings alongside the IconGadget. The exact layout ordering of the strings depends on the associated containing widget.
IconGadget uses the XmQTcontainer and XmQTspecifyRenderTable traits, and holds the XmQTcareParentVisual and XmQTcontainerItem traits.
Classes
IconGadget inherits behaviour, resources, and traits from Object, RectObject, and XmGadget classes.
The class pointer is xmIconGadgetClass.
The class name is XmIconGadget.
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 whether 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).
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
- XmNalignment
- Specifies the horizontal alignment of the pixmap with respect to the label when the icon is in LARGE_ICON view. Valid values are XmALIGNMENT_BEGINNING, XmALIGNMENT_CENTER, and XmALIGNMENT_END.
- XmNdetail
- Specifies an array of XmStrings that are the detail information associated with the gadget.
- XmNdetailCount
- Specifies the size of the XmNdetail array.
- XmNfontList
- Specifies the font list associated with XmIconGadget. The font list is an obsolete construct, and has been superseded by the render table. It is included for compatibility with earlier versions of Motif, and for applications that do not easily support render tables. The default font list is derived from the default render table, and if both a font list and a render table are specified, the render table takes precedence.
- XmNlabelString
- Specifies the compound string. If this value is NULL, it is initialized by converting the name of the gadget to a compound string. Refer to XmString(3) for more information on the creation and structure of compound strings.
- XmNlargeIconMask
- Specifies the icon mask used when XmNviewType is XmLARGE_ICON.
- XmNlargeIconPixmap
- Specifies the pixmap when XmNviewType is XmLARGE_ICON. If this resource's value is XmUNSPECIFIED_PIXMAP, there is no pixmap. If a large icon pixmap is specified, and if during conversion an associated mask can be fetched, then the XmNlargeIconMask resource is set to that mask.
- XmNmarginHeight
- Specifies the amount of vertical space between the highlight and the inside (pixmap and label).
- XmNmarginWidth
- Specifies the amount of horizontal space between the highlight and the inside (pixmap and label).
- XmNrenderTable
- Specifies the XmRenderTable of the text used in the gadget. If XmNrenderTable is NULL when the IconGadget is created, the parent's render table resource value is used if there is a render table. If the parent does not have a render table, the parent hierarchy of the widget is searched for a widget that holds the XmQTspecifyRenderTable trait. If such an ancestor is found, the render table is initialized to the XmLABEL_RENDER_TABLE value of the ancestor widget. If no such widget is found, the default is implementation dependent. Refer to XmRenderTable(3) for more information on the creation and structure of a XmRenderTable. If both a render table and a font list are specified, the render table will take precedence.
- XmNsmallIconMask
- Specifies the icon mask used when XmNviewType is XmSMALL_ICON.
- XmNsmallIconPixmap
- Specifies the pixmap when XmNviewType is XmSMALL_ICON. If this resource's value is XmUNSPECIFIED_PIXMAP, there is no pixmap. If a small icon pixmap is specified, and if during conversion an associated mask can be fetched, then the XmNsmallIconMask resource is set to that mask.
- XmNspacing
- Specifies the amount of space between the pixmap and the label parts of the icon.
- XmNviewType
-
Specifies the view (combination of pixmaps/text) that will be displayed.
If the IconGadget is a child of a Container widget, however, then the
specification of this resource will be taken from the Container---
if Container's XmNentryViewType is either XmLARGE_ICON or
XmSMALL_ICON, then IconGadget's XmNviewType takes that value;
otherwise, the default is XmLARGE_ICON.
This resource is set to one of the following:
-
- XmLARGE_ICON
- The pixmap specified by XmNlargeIconPixmap is displayed with the XmNlabelString beneath it.
- XmSMALL_ICON
- The pixmap specified by XmNsmallIconPixmap is displayed with the XmNlabelString displayed in the direction of the XmNlayoutDirection resource.
-
- XmNvisualEmphasis
-
Specifies the visual state of the IconGadget. If the IconGadget is in a
selected state
all visuals are displayed using the Container XmNselectColor
resource.
It is set to one of the following:
-
- XmSELECTED
- The IconGadget is in the selected state and displays the appropriate visuals.
- XmNOT_SELECTED
- The IconGadget is not in the selected state.
-
Inherited Resources
IconGadget inherits behavior and resources from the superclasses described in the following tables. For a complete description of each resource, refer to the reference page for that superclass.

Virtual Bindings
The bindings for virtual keys are vendor specific. For information about bindings for virtual buttons and keys, see VirtualBindings(3).
Errors/Warnings
The toolkit will display a warning if an incorrect value is given for an enumeration resource.
