Hello!
I want to open a text document and to display it on my window. The process has two actions: Opening the file and displaying it on the window. Theoritically, two slots are expected, and two bottons too to be clicked on. But practically, it seems not feasible, since a click on the open button should display the data on the window.
If I click on m_open (see below), a dialog window for the selection of the file will open. I have to selcet this file, click on "open" button of the Dialog window and then the window dissapears.

Line 8 of .cpp: The text erea shoul dremain hide until the data a ready to be display, and will appear with the line 25 of .cpp.
On the line 27 of .cpp file, I display the data on the window. If is not here, I must create another slot, that requires another button, because when I am connecting the button "m_open" to this slot (to open the file) and to another(to display the data), the compilation fails.

My questions:
1- Is there a way to connect the button open of the dialog window (when opening a file) to a slot in order to display my data on my window? If not, how to proceed?

Many thanks in advance.

Here is my code:

.h flie
Qt Code: 
  1. #ifndef DEF_MYWINDOW
  2.    #define DEF_MYWINDOW
  3.  
  4.    #include <QtGui>
  5.  
  6.  
  7.    class MyWindow: public QMainWindow
  8.    {
  9.    Q_OBJECT
  10.  
  11.    public:
  12.    explicit MyWindow();
  13.    virtual ~MyWindow();
  14.  
  15.    public slots:
  16.    void openFile();
  17.  
  18.    private:
  19.    QAction *m_open;
  20.    QTextEdit *m_myText;
  21.    QWidget *m_centralZone;
  22.    QMenu *m_menuFile; 
  23.    QLineEdit *m_openAFile;
  24.  
  25. };
  26.  
  27.    #endif // MYWINDOW_H
