/*!
Subclass of <a href="http://qt-project.org/doc/qt-5/qfiledialog.html">QFileDialog</a> which re-implements the static public functions. The reason for this
is that the <a href="http://qt-project.org/doc/qt-5/qfiledialog.html">QFileDialog</a> implementations of these use the native os dialogs. On OSX these
these can intermittently hang. So instead here we use the native dialogs. It also allows
use to catch these dialogs for unit testing.
@remark If you need to know what type of file was returned by these functions, you can use something like:
@code{.cpp}
QString filename = QGCQFileDialog::getSaveFileName(this, tr("Save File"), "~/", "Foo files (*.foo);;All Files (*.*)", "foo");
if (!filename.isEmpty()) {
QFileInfo fi(filename);
QString fileExtension(fi.suffix());
if (fileExtension == QString("foo")) {
// do something
}
}

@param[in] defaultSuffix Specifies a string that will be added to the filename if it has no suffix already. The suffix is typically used to indicate the file type (e.g. "txt" indicates a text file).

@remark If a default suffix is given, it will be appended to the filename if the user does not enter one themselves. That is, if the user simply enters \e foo and the default suffix is set to \e bar,
the returned filename will be \e foo.bar. However, if the user specifies a suffix, the \e strict flag will determine what is done. If the user enters \e foo.txt and \e strict is false, the function
returns \e foo.txt (no suffix enforced). If \e strict is true however, the default suffix is appended no matter what. In the case above, the function will return \e foo.txt.bar (suffix enforced).
@remark If \e strict is set and the file name given by the user is renamed (the \e foo.txt.bar example above), the function will check and see if the file already exists. If that's the case, it will
ask the user if they want to overwrite it.
