Detailed Description

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 to select only existing directories. wxGTK control always adds this flag internally as it does not support its absence.
• 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.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxFileDirPickerEvent& event)

Event macros for events emitted by this class:

• EVT_DIRPICKER_CHANGED(id, func):
  The user changed the directory selected in the control either using the button or using text control (see wxDIRP_USE_TEXTCTRL; note that in this case the event is fired only if the user's input is valid, e.g. an existing directory path).

Member Function Documentation

bool wxDirPickerCtrl::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxString &	path = wxEmptyString,
		const wxString &	message = wxDirSelectorPromptStr,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxDIRP_DEFAULT_STYLE,
		const wxValidator &	validator = wxDefaultValidator,
		const wxString &	name = wxDirPickerCtrlNameStr
	)

Creates the widgets with the given parameters.

Parameters:

parent	Parent window, must not be non-NULL.
id	The identifier for the control.
path	The initial directory shown in the control. Must be a valid path to a directory or the empty string.
message	The message shown to the user in the wxDirDialog shown by the control.
pos	Initial position.
size	Initial size.
style	The window style, see wxDIRP_* flags.
validator	Validator which can be used for additional date checks.
name	Control name.

Returns:

true if the control was successfully created or false if creation failed.

wxFileName wxDirPickerCtrl::GetDirName

(

)

const

Returns the absolute path of the currently selected directory as a wxFileName object.

This function is equivalent to GetPath().

wxString wxDirPickerCtrl::GetPath

(

)

const

Returns the absolute path of the currently selected directory.

void wxDirPickerCtrl::SetDirName

(

const wxFileName &

dirname

)

Just like SetPath() but this function takes a wxFileName object.

void wxDirPickerCtrl::SetInitialDirectory

(

const wxString &

dir

)

Set the directory to show when starting to browse for directories.

This function is mostly useful for the directory picker controls which have no selection initially to configure the directory that should be shown if the user starts browsing for directories as otherwise the initially selected directory is used, which is usually the desired behaviour and so the directory specified by this function is ignored in this case.

Since:

2.9.4

void wxDirPickerCtrl::SetPath

(

const wxString &

dirname

)

Sets the absolute path of (the default converter uses current locale's charset)the currently selected directory.

This must be a valid directory if wxDIRP_DIR_MUST_EXIST style was given.
