Access widgets

[Gayathri]

Hi,
Please let me know how to access widgets in other dialogs?

Thanks in advance

Easiest is to provide a pointer to the widget(s) in the dialog constructor and, for example, save the pointer in a member variable of your class which is derived from QDialog. This way all methods of your dialog class can access the widget(s).

Header file



class MyDialog : public QDialog
{
Q_OBJECT

public: // Operations

// ctor
MyDialog(QWidget* parent, QWidget* myOtherWidget);


private: // Attributes

QWidget* m_otherWidget;

....


Implementation file



MyDialog::MyDialog(QWidget* parent, QWidget* myOtherWidget)
: QDialog(parent),
m_otherWidget(myOtherWidget)
{
...

m_otherWidget->callWhateverMethodIsAccessibleFromThatWidget();

...
}

Windows are just normal classes, so you can do it just like if you were accessing data stored in some other class.

Remember that usually you don't want to access other window's widgets directly, since it's an implementation detail that should be hidden from other classes.
