wxFilePickerCtrl(3)

NAME
wxFilePickerCtrl - This control allows the user to select a file.

DESCRIPTION

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 and wxOSX, 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 file selected in the popup wxFileDialog must be an existing file. Notice that it still remains possible for the user to enter a non-existent file name in the text control if wxFLP_USE_TEXTCTRL is also used, this flag is a hint for the user rather than a guarantee that the selected file does exist for the program.

    • 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.

DATA TYPES

wxFilePickerCtrl() :: wx:wx_object().

FUNCTIONS

create(This, Parent, Id, [Option]) -> boolean() when This :: wxFilePickerCtrl(), Parent :: wxWindow:wxWindow(), Id :: integer(), Option :: {path, unicode:chardata()} | {message, unicode:chardata()} | {wildcard, unicode:chardata()} | {pos, {X :: integer(), Y :: integer()}} | {size, {W :: integer(), H :: integer()}} | {style, integer()} | {validator, wx:wx_object()}.

    Creates this widget with the given parameters.

    Return: true if the control was successfully created or false if creation failed.
destroy(This :: wxFilePickerCtrl()) -> ok.

    Destroys the object
getPath(This) -> unicode:charlist() when This :: wxFilePickerCtrl().

    Returns the absolute path of the currently selected file.
new() -> wxFilePickerCtrl().
new(Parent, Id, [Option]) -> wxFilePickerCtrl() when Parent :: wxWindow:wxWindow(), Id :: integer(), Option :: {path, unicode:chardata()} | {message, unicode:chardata()} | {wildcard, unicode:chardata()} | {pos, {X :: integer(), Y :: integer()}} | {size, {W :: integer(), H :: integer()}} | {style, integer()} | {validator, wx:wx_object()}.

    Initializes the object and calls create/4 with all the parameters.
setPath(This, Filename) -> ok when This :: wxFilePickerCtrl(), Filename :: unicode:chardata().

    Sets the absolute path of the currently selected file.

    If the control uses wxFLP_FILE_MUST_EXIST and does not use wxFLP_USE_TEXTCTRL style, the filename must be a name of an existing file and will be simply ignored by the native wxGTK implementation if this is not the case (the generic implementation used under the other platforms accepts even invalid file names currently, but this is subject to change in the future, don't rely on being able to use non-existent paths with it).
