Detailed Description

This control allows the user to select a file.

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

Styles

This class supports the following styles:

• wxFLP_DEFAULT_STYLE:
  The default style: includes wxFLP_OPEN | wxFLP_FILE_MUST_EXIST and, under wxMSW only, wxFLP_USE_TEXTCTRL.
• wxFLP_USE_TEXTCTRL:
  Creates a text control to the left of the picker button which is completely managed by the wxFilePickerCtrl 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.
• wxFLP_OPEN:
  Creates a picker which allows the user to select a file to open.
• wxFLP_SAVE:
  Creates a picker which allows the user to select a file to save.
• wxFLP_OVERWRITE_PROMPT:
  Can be combined with wxFLP_SAVE only: ask confirmation to the user before selecting a file.
• wxFLP_FILE_MUST_EXIST:
  Can be combined with wxFLP_OPEN only: the selected file must be an existing file.
• wxFLP_CHANGE_DIR:
  Change current working directory on each user file selection change.
• wxFLP_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_FILEPICKER_CHANGED(id, func):
  The user changed the file selected in the control either using the button or using text control (see wxFLP_USE_TEXTCTRL; note that in this case the event is fired only if the user's input is valid, e.g. an existing file path if wxFLP_FILE_MUST_EXIST was given).

Member Function Documentation

bool wxFilePickerCtrl::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxString &	path = wxEmptyString,
		const wxString &	message = wxFileSelectorPromptStr,
		const wxString &	wildcard = wxFileSelectorDefaultWildcardStr,

		const wxSize &	size = wxDefaultSize,
		long	style = wxFLP_DEFAULT_STYLE,
		const wxValidator &	validator = wxDefaultValidator,
		const wxString &	name = wxFilePickerCtrlNameStr
	)

Creates this widget with the given parameters.

Parameters:

parent	Parent window, must not be non-NULL.
id	The identifier for the control.
path	The initial file shown in the control. Must be a valid path to a file or the empty string.
message	The message shown to the user in the wxFileDialog shown by the control.
wildcard	A wildcard which defines user-selectable files (use the same syntax as for wxFileDialog's wildcards).
pos	Initial position.
size	Initial size.
style	The window style, see wxFLP_* flags.
validator	Validator which can be used for additional data checks.
name	Control name.

Returns:

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

wxFileName wxFilePickerCtrl::GetFileName

(

)

const

Similar to GetPath() but returns the path of the currently selected file as a wxFileName object.

wxString wxFilePickerCtrl::GetPath

(

)

const

Returns the absolute path of the currently selected file.

void wxFilePickerCtrl::SetFileName

(

const wxFileName &

filename

)

This method does the same thing as SetPath() but takes a wxFileName object instead of a string.

void wxFilePickerCtrl::SetInitialDirectory

(

const wxString &

dir

)

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

This function is mostly useful for the file picker controls which have no selection initially to configure the directory that should be shown if the user starts browsing for files as otherwise the directory of initially selected file 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 wxFilePickerCtrl::SetPath

(

const wxString &

filename

)

Sets the absolute path of the currently selected file.

This must be a valid file if the wxFLP_FILE_MUST_EXIST style was given.
