Qt, can't display child widget
- by Blin
I have two widgets defined as follows
class mainWindow : public QWidget
{
Q_OBJECT
public:
mainWindow();
void readConfig();
private:
SWindow *config;
QVector <QString> filePath;
QVector <QLabel*> alias,procStatus;
QVector <int> delay;
QGridLayout *mainLayout;
QVector<QPushButton*> stopButton,restartButton;
QVector<QProcess*> proc;
QSignalMapper *stateSignalMapper, *stopSignalMapper, *restartSignalMapper;
public slots:
void openSettings();
void startRunning();
void statusChange(int);
void stopProc(int);
void restartProc(int);
void renew();
};
class SWindow : public QWidget
{
Q_OBJECT
public:
SWindow(QWidget *parent=0);
void readConfig();
void addLine(int);
private:
QVector<QPushButton*> selectButton;
QVector<QLabel*> filePath;
QVector<QLineEdit*> alias;
QSignalMapper *selectSignalMapper;
QVector<QSpinBox*> delay;
QGridLayout *mainLayout;
public slots:
void selectFile(int);
void saveFile();
void addLineSlot();
};
when i create and display SWindow object from mainWindow like this
void mainWindow::openSettings()
{
config = new SWindow();
config->show();
}
everything is ok, but now i need to access the mainWindow from SWindow, and
void mainWindow::openSettings()
{
config = new SWindow(this);
config->show();
}
doesn't display SWindow. How can i display SWindow?
How do i call a function on widget close?
