NAME
XmPrimitive — The Primitive widget class "XmPrimitive" "widget class" "Primitive"
SYNOPSIS
#include <Xm/Xm.h>
DESCRIPTION
Primitive is a widget class used as a supporting superclass for other widget classes. It
handles border drawing and highlighting, traversal activation and deactivation, and
various callback lists needed by Primitive widgets. Primitive and all its subclasses hold
the XmQTcareParentVisual trait.
Data Transfer Behavior
Primitive has no widget class conversion or destination procedure. Subclasses and the
XmNconvertCallback procedures are responsible for any conversion of selections.
Subclasses and the subclass XmNdestinationCallback procedures are responsible for any data
transfers to the widget.
Classes
Primitive inherits behavior, resources, and traits from Core.
The class pointer is xmPrimitiveWidgetClass.
The class name is XmPrimitive.
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).

└────────────────────────┴───────────────────────┴──────────────────┴──────────────────────┴────────┘
XmNbottomShadowColor
Specifies the color to use to draw the bottom and right sides of the border
shadow. This color is used if the XmNtopShadowPixmap resource is unspecified.
XmNbottomShadowPixmap
Specifies the pixmap to use to draw the bottom and right sides of the border
shadow.
XmNconvertCallback
Specifies a list of callbacks called when the widget is asked to convert a
selection. The type of the structure whose address is passed to these callbacks
is XmConvertCallbackStruct. The reason is XmCR_OK.
XmNforeground
Specifies the foreground drawing color used by Primitive widgets.
XmNhelpCallback
Specifies the list of callbacks that is called when the help key is pressed. The
reason sent by the callback is XmCR_HELP.
XmNhighlightColor
Specifies the color of the highlighting rectangle. This color is used if the
highlight pixmap resource is XmUNSPECIFIED_PIXMAP.
XmNhighlightOnEnter
Specifies if the highlighting rectangle is drawn when the cursor moves into the
widget. If the shell's focus policy is XmEXPLICIT, this resource is ignored,
and the widget is highlighted when it has the focus. If the shell's focus
policy is XmPOINTER and if this resource is True, the highlighting rectangle is
drawn when the cursor moves into the widget. If the shell's focus policy is
XmPOINTER and if this resource is False, the highlighting rectangle is not drawn
when the the cursor moves into the widget. The default is False.
XmNhighlightPixmap
Specifies the pixmap used to draw the highlighting rectangle.
XmNhighlightThickness
Specifies the thickness of the highlighting rectangle.
XmNlayoutDirection
Specifies the direction in which components of the primitive (including strings)
are laid out. The values are of type XmDirection. If the widget's parent is a
primitive or shell, the value is inherited from the widget's parent. Otherwise,
it is inherited from the closest ancestor vendor or menu shell. Refer to the
XmDirection(3) reference page for the possible direction values.
XmNnavigationType
Determines whether the widget is a tab group.
XmNONE Indicates that the widget is not a tab group.
XmTAB_GROUP
Indicates that the widget is a tab group, unless the XmNnavigationType
of another widget in the hierarchy is XmEXCLUSIVE_TAB_GROUP.
XmSTICKY_TAB_GROUP
Indicates that the widget is a tab group, even if the
XmNnavigationType of another widget in the hierarchy is
XmEXCLUSIVE_TAB_GROUP.
XmEXCLUSIVE_TAB_GROUP
Indicates that the widget is a tab group and that widgets in the
hierarchy whose XmNnavigationType is XmTAB_GROUP are not tab groups.
When a parent widget has an XmNnavigationType of
XmEXCLUSIVE_TAB_GROUP, traversal of non-tab-group widgets within the
group is based on the order of those widgets in their parent's
XmNchildren list.
When the XmNnavigationType of any widget in a hierarchy is
XmEXCLUSIVE_TAB_GROUP, traversal of tab groups in the hierarchy
proceeds to widgets in the order in which their XmNnavigationType
resources were specified as XmEXCLUSIVE_TAB_GROUP or
XmSTICKY_TAB_GROUP, whether by creating the widgets with that value,
by calling XtSetValues, or by calling XmAddTabGroup.
XmNpopupHandlerCallback
Allows the application to control which popup menu will be automatically posted.
The reason can either be XmCR_POST or XmCR_REPOST:
XmCR_POST Indicates that this is a regular posting request.
XmCR_REPOST
Indicates that the menu was just unposted and that this callback was
invoked on a replay.
This callback uses the XmPopupHandlerCallbackStruct structure to pass
information.
XmNshadowThickness
Specifies the size of the drawn border shadow.
XmNtoolTipString
The XmString to display as the toolTip. If this resource is NULL, no tip will be
displayed. ToolTips are described in VendorShell(3)
XmNtopShadowColor
Specifies the color to use to draw the top and left sides of the border shadow.
This color is used if the XmNtopShadowPixmap resource is unspecified. If a
default top shadow pixmap exists, it will need to be removed for the
XmNtopShadowColor to take effect.
XmNtopShadowPixmap
Specifies the pixmap to use to draw the top and left sides of the border shadow.
A Primitive top shadow pixmap is created in two situations. In either of these
situations, a default 50-foreground top shadow pixmap is created.
· If the Primitive top shadow color is the same as the Core background pixel
color.
· If the depth of the screen is only one.
For example, if a widget with the same top shadow and background color is
created, a default shadow pixmap is generated. Such a pixmap needs to be removed
for the XmNtopShadowColor resource to take effect.
XmNtraversalOn
Specifies if traversal is activated for this widget. In CascadeButton and
CascadeButtonGadget, this resource is forced to True unless the parent is an
OptionMenu.
XmNunitType
Provides the basic support for resolution independence. It defines the type of
units a widget uses with sizing and positioning resources. If the widget's
parent is a subclass of XmManager and if the XmNunitType resource is not
explicitly set, it defaults to the unit type of the parent widget. If the
widget's parent is not a subclass of XmManager, the resource has a default unit
type of XmPIXELS.
The unit type can also be specified in resource files, with the following
format:
<floating value><unit>
where:
unit is <" ", pixels, inches, centimeters, millimeters, points, font units>
pixels is <pix, pixel, pixels>
inches is <in, inch, inches>
centimeter
is <cm, centimeter, centimeters>
millimeters
is <mm, millimeter, millimeters>
points is <pt, point, points>
font units
is <fu, font_unit, font_units>
float is {"+"|"-"}{{<"0"-"9">*}.}<"0"-"9">*
Note that the type Dimension must always be positive.
For example,
xmfonts*XmMainWindow.height: 10.4cm
*PostIn.width: 3inches
XmNunitType can have the following values:
XmPIXELS All values provided to the widget are treated as normal pixel values.
XmMILLIMETERS
All values provided to the widget are treated as normal millimeter
values.
Xm100TH_MILLIMETERS
All values provided to the widget are treated as 1/100 of a
millimeter.
XmCENTIMETERS
All values provided to the widget are treated as normal centimeter
values.
XmINCHES All values provided to the widget are treated as normal inch values.
Xm1000TH_INCHES
All values provided to the widget are treated as 1/1000 of an inch.
XmPOINTS All values provided to the widget are treated as normal point values.
A point is a unit used in text processing applications and is defined
as 1/72 of an inch.
Xm100TH_POINTS
All values provided to the widget are treated as 1/100 of a point. A
point is a unit used in text processing applications and is defined as
1/72 of an inch.
XmFONT_UNITS
All values provided to the widget are treated as normal font units. A
font unit has horizontal and vertical components. These are the
values of the XmScreen resources XmNhorizontalFontUnit and
XmNverticalFontUnit.
Xm100TH_FONT_UNITS
All values provided to the widget are treated as 1/100 of a font unit.
A font unit has horizontal and vertical components. These are the
values of the XmScreen resources XmNhorizontalFontUnit and
XmNverticalFontUnit.
XmNuserData
Allows the application to attach any necessary specific data to the widget. It
is an internally unused resource.
Dynamic Color Defaults
The foreground, background, top shadow, bottom shadow, and highlight color resources are
dynamically defaulted. If no color data is specified, the colors are automatically
generated. On a single-plane system, a black and white color scheme is generated.
Otherwise, four colors are generated, which display the correct shading for the 3-D
visuals. If the background is the only color specified for a widget, the top shadow and
bottom shadow colors are generated to give the 3-D appearance. Foreground and highlight
colors are generated to provide sufficient contrast with the background color.
Colors are generated only at creation. Resetting the background through XtSetValues does
not regenerate the other colors. XmChangeColor can be used to recalculate all associated
colors based on a new background color.
Inherited Resources
Primitive inherits behavior and resources from the superclass described in the following
table. For a complete description of each resource, refer to the reference page for that
superclass.
