GUIObject w => GUIObject (ICursor w)

Internal.

(HasInsertionCursor w, Widget w) => HasBorder (ICursor w)

The insertion cursor has a configureable borderwidth (width for three dimensional appearence).

(HasInsertionCursor w, Widget w) => HasSize (ICursor w)

The insertion cursor has a configureable width.

(HasInsertionCursor w, Widget w) => HasColour (ICursor w)

The insertion cursor has a configureable colour.

HasIndex (Entry a) (ICursor (Entry a)) BaseIndex

The entries insertion cursor is a valid index for an entry widget.

class Widget w => HasInsertionCursor w

Widgets with an insertion cursor instantiate the class HasInsertionCursor.

Instances

HasInsertionCursor Editor

An editor widget has an insertion cursor.

HasInsertionCursor (Entry a)

An entry widget has an insertion cursor.

class HasInsertionCursor w => HasInsertionCursorIndexGet w i where

Widgets from which you can get the index of the insertion cursor instantiate the class HasInsertionCursorIndexSet.

Methods

getInsertionCursor :: w -> IO i

Instances

HasInsertionCursorIndexGet Editor (Distance, Distance)

You can get the position of the insertion cursor of an editor widget.

HasInsertionCursorIndexGet (Entry a) Int

You can get the position of the insertion cursor of an entry widget.

class HasInsertionCursor w => HasInsertionCursorIndexSet w i where

Widgets with an insertion cursor that can be set to a specific index instantiate the class HasInsertionCursorIndexSet.

Methods

insertionCursor :: i -> Config w

Instances

HasIndex Editor i BaseIndex => HasInsertionCursorIndexSet Editor i

The insertion cursor of an editor widget can be set by a base index.

HasIndex (Entry a) i BaseIndex => HasInsertionCursorIndexSet (Entry a) i

insertOffTime :: HasInsertionCursor w => Int -> Config (ICursor w)

Sets the time the insertion cursor blinks off (in milliseconds, zero disables blinking).

getInsertOffTime :: HasInsertionCursor w => ICursor w -> IO Int

Gets the time the insertion cursor blinks off.

insertOnTime :: HasInsertionCursor w => Int -> Config (ICursor w)

Sets the time the insertion cursor blinks on (in milliseconds).

getInsertOnTime :: HasInsertionCursor w => ICursor w -> IO Int

Gets the time the insertion cursor blinks on.
