No real changes, just clean up sources by removing trailing spaces from all the non-generated files. This should hopefully avoid future commits mixing significant changes with insignificant whitespace ones.

/**
|
|
@class wxFilePickerCtrl
|
|
|
|
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 @c wxUSE_FILEPICKERCTRL is set to 1 (the default).
|
|
|
|
@beginStyleTable
|
|
@style{wxFLP_DEFAULT_STYLE}
|
|
The default style: includes wxFLP_OPEN | wxFLP_FILE_MUST_EXIST and,
|
|
under wxMSW and wxOSX, wxFLP_USE_TEXTCTRL.
|
|
@style{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.
|
|
@style{wxFLP_OPEN}
|
|
Creates a picker which allows the user to select a file to open.
|
|
@style{wxFLP_SAVE}
|
|
Creates a picker which allows the user to select a file to save.
|
|
@style{wxFLP_OVERWRITE_PROMPT}
|
|
Can be combined with wxFLP_SAVE only: ask confirmation to the user
|
|
before selecting a file.
|
|
@style{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 @c 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.
|
|
@style{wxFLP_CHANGE_DIR}
|
|
Change current working directory on each user file selection change.
|
|
@style{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.
|
|
@endStyleTable
|
|
|
|
|
|
@beginEventEmissionTable{wxFileDirPickerEvent}
|
|
@event{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).
