/* A portable library to create open and save dialogs on linux, osx and
|
|
* windows.
|
|
*
|
|
* The library define a single function : noc_file_dialog_open.
|
|
* With three different implementations.
|
|
*
|
|
* Usage:
|
|
*
|
|
* The library does not automatically select the implementation, you need to
|
|
* define one of those macros before including this file:
|
|
*
|
|
* NOC_FILE_DIALOG_GTK
|
|
* NOC_FILE_DIALOG_WIN32
|
|
* NOC_FILE_DIALOG_OSX

|
* filters : a list of strings separated by '\0' of the form:
|
|
* "name1 reg1 name2 reg2 ..."
|
|
* The last value is followed by two '\0'. For example,
|
|
* to filter png and jpeg files, you can use:
|
|
* "png\0*.png\0jpeg\0*.jpeg\0"
|
|
* You can also separate patterns with ';':
|
|
* "jpeg\0*.jpg;*.jpeg\0"
|
|
* Set to NULL for no filter.
|
|
* default_path : the default file to use or NULL.
|
|
* default_name : the default file name to use or NULL.
|
|
*
|
|
* The function return a C string. There is no need to free it, as it is
|
|
* managed by the library. The string is valid until the next call to
|
|
* no_dialog_open. If the user canceled, the return value is NULL.
