Each tab consists of a Primitive widget surrounded by tab decorations including an optional pixmap. Any non-Primitive widget children of the Folder are placed in the center area. The widgets contained in the tabs can be assigned a non-Primitive widget to display/manage when the tab widget is selected. .SS Class Information Folder inherits from XmManager, Constraint, Composite and Core. Its class pointer is xmlFolderWidgetClass. Its class name is XmLFolder. .SS New Resources .nf .ft B Name Class Type Default Access .ft P XmNactiveTab XmCActiveTab int -1 G XmNautoSelect XmCAutoSelect Boolean True CSG XmNblankBackground XmCBlankBackground Pixel dynamic CSG XmNblankBackgroundPixmap XmCBlankBackgroundPixmap Pixmap dynamic CSG XmNcornerDimension XmCCornerDimension Dimension 2 CSG XmNcornerStyle XmCCornerStyle unsigned char XmCORNER_ARC CSG XmNdebugLevel XmCDebugLevel int 0 CSG XmNfontList XmCFontList XmFontList dynamic CSG XmNhighlightThickness XmCHighlightThickness Dimension 2 CSG XmNinactiveBackground XmCInactiveBackground Pixel dynamic CSG XmNinactiveForeground XmCInactiveForeground Pixel dynamic CSG XmNmarginHeight XmCMarginHeight Dimension 0 CSG XmNmarginWidth XmCMarginWidth Dimension 0 CSG XmNpixmapMargin XmCPixmapMargin Dimension 2 CSG XmNresizePolicy XmCFolderResizePolicy XmRFolderResizePolicy XmRESIZE_STATIC CSG XmNrotateWhenLeftRight XmCRotateWhenLeftRight Boolean True CSG XmNspacing XmCSpacing Dimension 0 CSG XmNtabBarHeight XmCTabBarHeight Dimension dynamic G XmNtabCount XmCTabCount int 0 G XmNtabPlacement XmCTabPlacement unsigned char XmFOLDER_TOP CSG XmNtabsPerRow XmCTabsPerRow int 0 CSG XmNtabTranslations XmCTranslations XtTranslations [focus translations] CG XmNtabWidgetList XmCReadOnly WidgetList dynamic G .fi .IP XmNactiveTab The position of the currently active tab. The first tab on the left has a position of 0. If no tab is active, this value equals -1. .IP XmNautoSelect If True (the default), the Folder will activate its first tab when it is realized. No callback is generated by this action. If False, no initial tab will be activated. .IP XmNblankBackground The color of the area between tabs, around tabs, and between tabs and the edge of the Folder. .IP XmNblankBackgroundPixmap The pixmap to display as a background (tiled) in the blank background area. See XmNblankBackground. .IP XmNcornerDimension If XmNcornerStyle is XmCORNER_LINE, this value is used to determine the length of the lines that clip the corners of the tabs. The greater this value is, the longer the corner lines will be. If XmNcornerStyle is XmCORNER_ARC, this value is used to determine the sizes of the arcs in the corners of the tabs. If XmNcornerStyle is XmCORNER_NONE, this resource has no effect. .IP XmNcornerStyle Defines the type of corners on the individual tabs. Possible values: .nf XmCORNER_NONE /* no corners */ XmCORNER_LINE /* corners are beveled */ XmCORNER_ARC /* corners are round */ .fi .IP XmNdebugLevel If set to a value greater than 0, debugging messages will be printed to stderr. When set to 0 (the default) only error messages will be generated. .IP XmNfontList The default font list for tabs created with the XmLFolderAddTab() functions. Changing this value does not affect existing widgets. If this value is NULL, a font list is obtained from the nearest parent that is a subclass of BulletinBoard, MenuShell, or VendorShell. .IP XmNhighlightThickness The thickness of the highlight drawn around the Primitive widget contained in the active tab. When a Primitive widget is added to the Folder, its highlightThickness is set to 0. The Folder is responsible for drawing the highlight in the active tab. This is necessary because if the Primitive widget were allowed to draw the highlight, it would erase the highlight with an incorrect color. .IP XmNinactiveBackground The background color of inactive tabs. This value is initially set to the background color of the Folder widget. .IP XmNinactiveForeground The foreground color of inactive tabs. This value is initially set to the foreground color of the Folder widget. .IP XmNmarginHeight If tab placement is on the top or bottom, this value is the margin between tab widgets and the top of tabs, and between tab widgets and the bottom of tabs. If tab placement is on the left or right, this value is the margin between tab widgets and the left of tabs, and between tab widgets and the right of tabs. .IP XmNmarginWidth If tab placement is on the top or bottom, this value is the margin between tab widgets and the left of tabs, and between tab widgets and the right of tabs. If tab placement is on the left or right, this value is the margin between tab widgets and the top of tabs and between tab widgets and bottoms of tabs. .IP XmNpixmapMargin The margin between the tab widget and any pixmap to its left. .IP XmNresizePolicy This policy determines when the Folder should perform a request for a new size from its parent. A policy of XmRESIZE_STATIC (the default) will cause the Folder to initially request a size which includes the preferred size of its children and then reject any subsequent resize requests from its non-tab widget children. A policy of XmRESIZE_DYNAMIC will cause the Folder to resize itself to include the preferred size of any of its children whenever its children change size. A policy of XmRESIZE_NONE will cause the Folder to never generate a resize request and also will cause it not to perform geometry management on its non-tab widget children. Possible values: .nf XmRESIZE_NONE /* no resize requests and no placement or geometry management of non-tab children */ XmRESIZE_STATIC /* initially layout to include preferred size of children */ XmRESIZE_DYNAMIC /* dynamically resize as children request new size */ .fi .IP XmNrotateWhenLeftRight If True, XmDrawnButton based tabs (including tabs created with the XmLFolderAddTab() functions) will display their text vertically instead of horizontally if they are placed on the left or right of the Folder. This occurs when the Folder's XmNtabPlacement resource is XmFOLDER_LEFT or XmFOLDER_RIGHT. Tabs on the left would have their text drawn up and tabs on the right would have their text drawn down. If False, tabs are left oriented horizontally regardless of their placement. .IP XmNspacing The amount of space between tabs. .IP XmNtabBarHeight The height, in pixels, of the tab bar. If tab placement is on the left or right, this value is the width of the tab bar. This value may not be set and is only valid after the Folder has been managed and has performed its layout. .IP XmNtabCount The number of tabs displayed. .IP XmNtabPlacement Where to place the tabs. Possible values: .nf XmFOLDER_TOP /* top left to right */ XmFOLDER_BOTTOM /* bottom left to right */ XmFOLDER_LEFT /* left top to bottom */ XmFOLDER_RIGHT /* right top to bottom */ .fi .IP XmNtabsPerRow If set to 0 (the default), the Folder will place tabs in a single row one after another during layout. If non-zero, this value specifies the number of rows of tabs to appear in the Folder and the Folder will pad each row to the width of the Folder by proportionally sizing the tabs based on their contents and the width of the row. .IP XmNtabTranslations The translation table used to augment the translations of Primitive widgets added to the Folder. The Folder overrides the FocusIn and FocusOut translations of its Primitive widget children allowing it to draw and erase tab highlights. .IP XmNtabWidgetList The list of widgets contained inside the tabs. These widgets are subclasses of XmPrimitive. .SS Constraint Resources Folder defines the following constraint resources. .nf .ft B Name Class Type Default Access .ft P XmNtabFreePixmaps XmCTabFreePixmap Boolean False CSG XmNtabInactivePixmap XmCTabInactivePixmap Pixmap XmUNSPECIFIED_PIXMAP CSG XmNtabManagedName XmCTabManagedName String NULL CSG XmNtabManagedWidget XmCTabManagedWidget Widget NULL CSG XmNtabPixmap XmCTabPixmap Pixmap XmUNSPECIFIED_PIXMAP CSG .fi .IP XmNtabFreePixmaps If True, the Folder will call XFreePixmap on the XmNtabPixmap and XmNtabInactivePixmap pixmaps when this widget is destroyed. This value is set to True for tabs created by the XmLFolderAddBitmapTab() functions. .IP XmNtabInactivePixmap The pixmap to appear in the left of the tab when the tab is inactive. .IP XmNtabManagedName By setting a managed name on a tab widget and setting the same managed name on a Manager widget, you specify that the tab manages the Manager widget. You can also specify that a tab manages a specific Manager widget by setting the managed name on the tab widget to the name (XtName) of the Manager widget. If a tab widget has a managed name, the XmNtabManagedWidget resource of the tab widget is ignored. .IP XmNtabManagedWidget Specifies a widget to be managed when this widget is activated. When this widget is deactivated, its managed widget will be unmanaged. This resource allows Manager widgets contained in the center of the Folder to be attached to tabs, so when a user selects a tab its attached Manager widget will be displayed on the screen. .IP XmNtabPixmap The pixmap to appear in the left of the tab when the tab is active. .SS Callback Resources Folder defines the following callback resources. .nf .ft B Callback Reason .ft P XmNactivateCallback XmCR_ACTIVATE .fi .SS Callback Structure Each callback function is passed a pointer to the structure shown below. .nf typedef struct { int reason; /* callback reason */ XEvent *event; /* event callback or NULL */ int pos; /* position of tab to act */ int allowActivate; /* allow/disallow act (1/0) */ } XmLFolderCallbackStruct; .fi pos will be set to the position of the tab (with 0 as the first tab on the left) to activate for XmNactivateCallback callbacks. If allowActivate is set to 0 by the callback function, the tab will not be activated and the attempt to activate the given tab will be rejected. .SS Inherited Resources Folder inherits the resources shown below. .nf .ft B Resource From Resource From .ft P XmNaccelerators Core XmNinitialResourcePersist Core XmNancestorSensitive Core XmNinsertPosition Composite XmNbackground Core XmNmappedWhenManaged Core XmNbackgroundPixmap Core XmNnavagationType Manager XmNborderColor Core XmNnumChildren Composite XmNborderPixmap Core XmNscreen Core XmNborderWidth Core XmNsensitive Core XmNbottomShadowColor Manager XmNshadowThicknses Manager XmNbottomShadowPixmap Manager XmNstringDirection Manager XmNchildren Composite XmNtopShadowColor Manager XmNcolormap Core XmNtopShadowPixmap Manager XmNdepth Core XmNtranslations Core XmNdestroyCallback Core XmNtraversalOn Manager XmNforeground Manager XmNunitType Manager XmNheight Core XmNuserData Manager XmNhelpCallback Manager XmNwidth Core XmNhighlightColor Manager XmNx Core XmNhighlightPixmap Manager XmNy Core .fi .SS Folder Translations Folder defines the translations shown below. .nf .ft B Event Action .ft P BSelect Press XmLFolderActivate() .fi .SS Folder Primitive Translations Folder overrides the translations shown below for all of its Primitive widget children. .nf .ft B Event Action .ft P FocusIn PrimitiveFocusIn() XmLFolderPrimFocusIn() FocusOut PrimtiveFocusOut() XmLFolderPrimFocusOut() .fi .SS Action Routines Folder defines the actions shown below. .IP XmLFolderActivate() Activates the tab at the location of the event passed to the action routine. .IP XmLFolderPrimFocusIn() Draws a highlight around the given widget. .IP XmLFolderPrimFocusOut() Erases the highlight around the given widget. .SH "SEE ALSO" XmLCreateFolder(3X) XmLFolderAddBitmapTab(3X) XmLFolderAddBitmapTabForm(3X) XmLFolderAddTab(3X) XmLFolderAddTabForm(3X) XmLFolderSetActiveTab(3X)
