3 /// This is a small ROOT macro to use Qt 3.3 class: [QFileDialog](https://doc.qt.io/archives/3.3/qfiledialog.html)
4 /// See: [https://doc.qt.io/archives/3.3/qfiledialog.html#getOpenFileName](https://doc.qt.io/archives/3.3/qfiledialog.html#getOpenFileName)
5 ///
6 /// To use, invoke ACLiC from the ROOT prompt:
7 /// ~~~
8 /// root [] .x QtFileDialog.C++
9 /// ~~~
10 ///
11 /// To use it with no ACLiC, omit the trailing "++"
12 /// ~~~
13 /// root [] .x QtFileDialog.C
14 /// ~~~
15 ///
16 /// The QtFileDialog returns TString object that contains the selected file name.
17 /// returns its pointer.
18 /// The macro QtMultiFileDialog.C provides an advanced example.
19 ///
20 /// The full list of the Qt classes available from Cint is defined by
21 /// begin_html [by $ROOTSYS/cint/lib/qtclasses.h](http://root.bnl.gov/QtRoot/htmldoc/src/qtclasses.h.html)
22 ///
23 /// All Qt classes can be used from ACLiC though.
