View Source wxDirPickerCtrl (wx v2.4.3)

This control allows the user to select a directory.

The generic implementation is a button which brings up a wxDirDialog when clicked. Native implementation may differ but this is usually a (small) widget which give access to the dir-chooser dialog. It is only available if wxUSE_DIRPICKERCTRL is set to 1 (the default).

Styles

This class supports the following styles:

  • wxDIRP_DEFAULT_STYLE: The default style: includes wxDIRP_DIR_MUST_EXIST and, under wxMSW only, wxDIRP_USE_TEXTCTRL.

  • wxDIRP_USE_TEXTCTRL: Creates a text control to the left of the picker button which is completely managed by the wxDirPickerCtrl and which can be used by the user to specify a path (see SetPath). The text control is automatically synchronized with button's value. Use functions defined in wxPickerBase to modify the text control.

  • wxDIRP_DIR_MUST_EXIST: Creates a picker which allows selecting only existing directories in the popup wxDirDialog. Notice that, as with wxFLP_FILE_MUST_EXIST, it is still possible to enter a non-existent directory even when this file is specified if wxDIRP_USE_TEXTCTRL style is also used. Also note that if wxDIRP_USE_TEXTCTRL is not used, the native wxGTK implementation always uses this style as it doesn't support selecting non-existent directories.

  • wxDIRP_CHANGE_DIR: Change current working directory on each user directory selection change.

  • wxDIRP_SMALL: Use smaller version of the control with a small "..." button instead of the normal "Browse" one. This flag is new since wxWidgets 2.9.3.

setPath(This, Dirname)

View Source 
-spec setPath(This, Dirname) -> ok when This :: wxDirPickerCtrl(), Dirname :: unicode:chardata().

Sets the absolute path of the currently selected directory.

If the control uses wxDIRP_DIR_MUST_EXIST and does not use wxDIRP_USE_TEXTCTRL style, the dirname must be a name of an existing directory and will be simply ignored by the native wxGTK implementation if this is not the case.
