added demo for it in the sample and documented 2. wxMimeTypeManager works a bit better under Windows (doesn't ignore the extensions without filetypes) git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@4850 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

\wxheading{Remarks}
|
|
|
|
Pops up a file selector box. In Windows, this is the common file selector
|
|
dialog. In X, this is a file selector box with somewhat less functionality.
|
|
The path and filename are distinct elements of a full file pathname.
|
|
If path is ``", the current directory will be used. If filename is ``",
|
|
no default filename will be supplied. The wildcard determines what files
|
|
are displayed in the file selector, and file extension supplies a type
|
|
extension for the required filename. Flags may be a combination of wxOPEN,
|
|
wxSAVE, wxOVERWRITE\_PROMPT, wxHIDE\_READONLY, wxMULTIPLE or 0.
|
|
|
|
Both the X and Windows versions implement a wildcard filter. Typing a
|
|
filename containing wildcards (*, ?) in the filename text item, and
|
|
clicking on Ok, will result in only those files matching the pattern being
|
|
displayed. The wildcard may be a specification for multiple
|
|
types of file with a description for each, such as:
|
|
|
|
\begin{verbatim}
|
|
"BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
|
|
\end{verbatim}
