Close button pressed signal in the QDockWidget

cincirin

"QMainWindow::removeDockWidget":http://doc.qt.nokia.com/stable/qmainwindow.html#removeDockWidget is not good ?

bq. Removes the dockwidget from the main window layout and hides it. Note that the dockwidget is not deleted.

No, i dont remove QDockWidgte at all, i need to control changing of visible

cincirin

Try something like this:
@
QAction dockWidgetAction = yourDockWidget->toggleViewAction();
dockWidgetAction->toogle();
@

Thank you for your help!
It is worked!

cincirin

You are welcome.
btw. nice virtual keyboard :-)

Ruzik

If this is an allusion to agglomerate interface, it will be configured :-)

I have one problem:
If user want to moved QDockWidget from QMainWindow to separate window: at first, widget become invisible and then redrawn as separate window
But how will I know when it is redrawn, and when the user closes it, if I get the same signals?

My current code:
RMathDockWidget.h
@#ifndef RMATHDOCKWIDGET
#define RMATHDOCKWIDGET

#include "QDockWidget"

class RMathDockWidget : public QDockWidget
{
Q_OBJECT
public:
RMathDockWidget(QWidget *parent = 0, Qt::WFlags flags=0);
~RMathDockWidget();
private:
bool localVisible;

QWidget * parentWidget;
public slots:
void setVisible(bool);
protected slots:
void checkedToVisible(bool);
};
#endif@
RMathDockWidget.cpp
@#include "RMathDockWidget.h"
#include "QDebug"
#include "QAction"
#include "Geter/Geter.h"

RMathDockWidget::RMathDockWidget(QWidget *parent, Qt::WFlags flags) : QDockWidget(parent,flags)
{
localVisible = true;
if(!parent)
{
qDebug() << "[Rizek message]Empty parent of RMathDockWidget!";
}
else
parentWidget = parent;

this->setMinimumWidth(120);
connect(parent, SIGNAL(activityChanged(bool)), this ,SLOT(setVisible(bool)));
connect(this, SIGNAL(visibilityChanged(bool)), this, SLOT(checkedToVisible(bool)));
this->setVisible(false);
}
RMathDockWidget::~RMathDockWidget()
{

}
void RMathDockWidget::setVisible(bool b)
{
//qDebug() << b << "!" << localVisible;
if (b && localVisible)
QDockWidget::setVisible(true);
else
QDockWidget::setVisible(false);
}
void RMathDockWidget::checkedToVisible(bool is)
{
qDebug() << is;
Geter g; //object for getting parent Window class
bool isParentWidgetVisible;
if(g.getRizekMath()->getTabWidget()->currentWidget() == parentWidget) //is current tab of tabWidget is active
isParentWidgetVisible = true;
else
isParentWidgetVisible = false;
if (isParentWidgetVisible)
localVisible = is;
}@

Exactly, are there no any ways to get signal from QDockWidget/Close Button when user click to this button?

Ruzik

Maybe, somehow we can determine when the widget becomes invisible due to the repainting, or when the user wanted it

cincirin

Why you do not use "QAction::toggled":http://doc.qt.nokia.com/latest/qaction.html#toggled signal ?
@
QAction dockWidgetAction = yourDockWidget->toggleViewAction();
QObject::connect(dockWidgetAction, SIGNAL(toogled(bool)), yourClassPointer, SLOT(dockWidgetToogled(bool))
@

Ruzik

Because, signal void QDockWidget::visibilityChanged ( bool visible ) simular it, and i use this signal
If i write it
@connect(this, SIGNAL(visibilityChanged(bool)), this, SLOT(checkedToVisible(bool)));@
instead of
@connect(dockWidgetAction, SIGNAL(toogled(bool)), yourClassPointer, SLOT(dockWidgetToogled(bool))@
There are no to change or i dont right?

cincirin

QDockWidget::visibilityChanged is fired

bq. as well as when it is docked in a tabbed dock area and its tab becomes selected or unselected.

It was my mistake - override setVisible()
Once again thank you for your help!
