Functions for wxNavigationKeyEvent class

This event class contains information about navigation events, generated by navigation keys such as tab and page down.

This event is mainly used by wxWidgets implementations. A wxNavigationKeyEvent handler is automatically provided by wxWidgets when you enable keyboard navigation inside a window by inheriting it from wxNavigationEnabled<>.

See: wxWindow:navigate/2, wxWindow::NavigateIn (not implemented in wx)

This class is derived (and can use functions) from: wxEvent

Types

wxNavigationKey()

-type wxNavigationKey() ::
    #wxNavigationKey{type :: wxNavigationKeyEvent:wxNavigationKeyEventType(),
                     dir :: boolean(),
                     focus :: wxWindow:wxWindow()}.

wxNavigationKeyEvent()

-type wxNavigationKeyEvent() :: wx:wx_object().

wxNavigationKeyEventType()

-type wxNavigationKeyEventType() :: navigation_key.

Functions

getCurrentFocus(This)

-spec getCurrentFocus(This) -> wxWindow:wxWindow() when This :: wxNavigationKeyEvent().

Returns the child that has the focus, or NULL.

getDirection(This)

-spec getDirection(This) -> boolean() when This :: wxNavigationKeyEvent().

Returns true if the navigation was in the forward direction.

isFromTab(This)

-spec isFromTab(This) -> boolean() when This :: wxNavigationKeyEvent().

Returns true if the navigation event was from a tab key.

This is required for proper navigation over radio buttons.

isWindowChange(This)

-spec isWindowChange(This) -> boolean() when This :: wxNavigationKeyEvent().

Returns true if the navigation event represents a window change (for example, from Ctrl-Page Down in a notebook).

setCurrentFocus(This, CurrentFocus)

-spec setCurrentFocus(This, CurrentFocus) -> ok
                   when This :: wxNavigationKeyEvent(), CurrentFocus :: wxWindow:wxWindow().

Sets the current focus window member.

setDirection(This, Direction)

-spec setDirection(This, Direction) -> ok when This :: wxNavigationKeyEvent(), Direction :: boolean().

Sets the direction to forward if direction is true, or backward if false.

setFromTab(This, FromTab)

-spec setFromTab(This, FromTab) -> ok when This :: wxNavigationKeyEvent(), FromTab :: boolean().

Marks the navigation event as from a tab key.

setWindowChange(This, WindowChange)

-spec setWindowChange(This, WindowChange) -> ok
                   when This :: wxNavigationKeyEvent(), WindowChange :: boolean().

Marks the event as a window change event.
