Arrow directions for the arrow widget

Child widget attach options for table containers

Whenever a container has some form of natural row it may align children in that row along a common typographical baseline. If the amount of verical space in the row is taller than the total requested height of the baseline-aligned children then it can use a BaselinePosition to select where to put the baseline inside the extra availible space.

Mouse buttons.

Dictate the style that a ButtonBox uses to align it contents

Specify which items of a calendar should be displayed.

Type of mouse click

Specifies in which corner a child widget should be placed

Editing option

The DestDefaults enumeration specifies the various types of action that will be taken on behalf of the user for a drag destination site.

• DestDefaultMotion: If set for a widget, GTK+, during a drag over this widget will check if the drag matches this widget's list of possible targets and actions. GTK+ will then call dragStatus as appropriate.
• DestDefaultHighlight: If set for a widget, GTK+ will draw a highlight on this widget as long as a drag is over this widget and the widget drag format and action are acceptable.
• DestDefaultDrop: If set for a widget, when a drop occurs, GTK+ will will check if the drag matches this widget's list of possible targets and actions. If so, GTK+ will call dragGetData on behalf of the widget. Whether or not the drop is successful, GTK+ will call dragFinish. If the action was a move, then if the drag was successful, then True will be passed for the delete parameter to dragFinish
• DestDefaultAll: If set, specifies that all default actions should be taken.

Packing parameters of a widget

• The Packing parameter determines how the child behaves in the horizontal or vertical way in an HBox or VBox, respectively. PackNatural means the child is as big as it requests. It will stay at the start or end of a Box if there is more space available. All children packed with PackRepel will be padded on both sides with additional space. PackGrow will increase the size of a widget so that it covers the available space. A menu bar, for instance, should always stay at the top of a window and should only occupy as little space as possible. Hence it should be packed at the start of a VBox with the packing option PackNatural. The working area of a window (e.g. the text area in an editor) should expand when the window is resized. Here the packing option PackGrow is the right choice and it is irrelevant whether the main area is inserted at the start or the end of a box. Finally PackRepel is most useful in a window where no widget can make use of excess space. Examples include a dialog box without list boxes or text fields.

Widget identification path

I don't have a clue.

Resize mode, for containers

• ResizeParent Pass resize request to the parent
• ResizeQueue Queue resizes on this widget
• ResizeImmediate Perform the resizes now

Scrolling type

Scrolling step

Mode in which selections can be performed

• There is a deprecated entry SelectionExtended which should have the same value as SelectionMultiple. C2HS chokes on that construct.

Shadow types

Describes a widget state. Widget states are used to match the widget against CSS pseudo-classes. Note that GTK extends the regular CSS classes and sometimes uses different names.

Whether to clamp or ignore illegal values.

Spin a SpinButton with the following method.

The TargetFlags enumeration is used to specify constraints on an entry in a TargetList. These flags are only used for drag and drop.

• If the TargetSameApp flag is set, the target will only be selected for drags within a single application.
• If the TargetSameWidget flag is set, the target will only be selected for drags within a single widget.

Specify the way the search function for TextBuffer works.

Where to place the toolbar?

Wether columns of a tree or list widget can be resized.

Window position types

Interaction of a window with window manager

Determine how lines are wrapped in a TextView.

Specifies the side of the entry at which an icon is placed.

How focus is crossing the widget.

Used in DragContext to indicate the protocol according to which DND is done.

Specify which events a widget will emit signals on.

Keyboard modifiers that are depressed when the user presses a key or a mouse button.

• This data type is used to build lists of modifers that were active during an event.
• The Apple key on Macintoshs is mapped to Alt2 and the Meta key (if available).
• Since Gtk 2.10, there are also Super, Hyper and Meta modifiers which are simply generated from Alt .. Compose modifier keys, depending on the mapping used by the windowing system. Due to one key being mapped to e.g. Alt2 and Meta, you shouldn't pattern match directly against a certain key but check whether a key is in the list using the elem function, say.

Information on from what level of the widget hierarchy the mouse cursor came.

NotifyAncestor

The window is entered from an ancestor or left towards an ancestor.

NotifyVirtual

The pointer moves between an ancestor and an inferior of the window.

NotifyInferior

The window is entered from an inferior or left towards an inferior.

NotifyNonlinear

The window is entered from or left towards a window which is neither an ancestor nor an inferior.

NotifyNonlinearVirtual

The pointer moves between two windows which are not ancestors of each other and the window is part of the ancestor chain between one of these windows and their least common ancestor.

NotifyUnknown

The level change does not fit into any of the other categories or could not be determined.

Determines a window edge or corner.

Defines the reference point of a window and the meaning of coordinates passed to windowMove. See windowMove and the "implementation notes" section of the extended window manager hints specification for more details.
