QtitanDocking2.3.0+QtitanRibbon5.0.0: Crash when panel is shown/hidden was created by Jörn
This code crashes when TestAct is toggled.

:h
#pragma once

#include <QtitanRibbon.h>
#include <QtitanDocking.h>


class GuiTest : public RibbonMainWindow
{
Q_OBJECT

public:
GuiTest(QWidget *parent = Q_NULLPTR);

private:
Ui::GuiTest ui;
DockPanelManager *dockPanelManager;
DockWidgetPanel* dockPanel1;
QAction *TestAct;

public slots:
void panelActionTriggered();

};


:cpp

#include <QtitanRibbon.h>
#include <QtitanDocking.h>

GuiTest::GuiTest(QWidget *parent)
: RibbonMainWindow(parent)
{
QLatin1String m_defaultStyle("windowsvista");
qApp->style()->setObjectName(m_defaultStyle);

ui.setupUi(this);

setWindowTitle("QtitanRibbon + QtitanDocking");

ribbonBar()->setFrameThemeEnabled(true);
ribbonBar()->setTitleBarVisible(true);

QWidget *widget = new QWidget;
dockPanelManager = new DockPanelManager(widget);
dockPanelManager->setDockPanelTransparentWhileDragging(true);
dockPanelManager->setArrowMarkersShown(true);
dockPanelManager->setDockPanelFullContentsWhileDraggingShown(true);
setCentralWidget(widget);

dockPanelManager->centralLayoutPanel();

////// 2 - Creating a ribbon
ribbonBar()->setFrameThemeEnabled();
RibbonPage *page = ribbonBar()->addPage("&Buttons1");

////// 3 - Creating a dockBarManager
DockBarManager* managerBar = new DockBarManager(widget);
DockToolBar* tooBar = managerBar->addToolBar("My Toolbar", Qtitan::DockBarTop);
TestAct = tooBar->addAction("Button");
TestAct->setCheckable(true);
TestAct->setChecked(true);
connect(TestAct, SIGNAL(triggered()), this, SLOT(panelActionTriggered()));

////// 4 - Creating a panelManager
DockWidgetPanel* dockPanel1 = dockPanelManager->addDockPanel("My Panel_1", Qtitan::LeftDockPanelArea);
dockPanel1->setWidget(new QLabel("panel1"));
DockWidgetPanel* dockPanel2 = dockPanelManager->addDockPanel("My Panel_2", Qtitan::RightDockPanelArea);
dockPanel2->setWidget(new QLabel("panel2"));


}

void GuiTest::panelActionTriggered()
{
if (TestAct->isChecked())
dockPanelManager->showDockPanel(dockPanel1);
else
dockPanel1->closePanel();
}

The Code is wrong.
dockPanel1 is a member of GuiTest but is redefined in GuiTest::GuiTest
////// 4 - Creating a panelManager
DockWidgetPanel *dockPanel1 = dockPanelManager->addDockPanel("My Panel_1", Qtitan::LeftDockPanelArea);
^^^^^^^^^^^^^^^^^^ <- wrong

panel shown/hidden work well with following codes
if(state == Qt::Checked)
{
if( Qtitan::DockWidgetPanel* panel = qobject_cast<Qtitan::DockWidgetPanel*>(pPane) )
{
panel->showPanel();
}
}
else
{
if( Qtitan::DockWidgetPanel* panel = qobject_cast<Qtitan::DockWidgetPanel*>(pPane) )
{
panel->closePanel();
}
}

change to this code
dockPanelManager = new Qtitan::DockPanelManager(qobject_cast<QMainWindow*>(parent));
can not work，dockPanel not show in the RibbonMainWindow frame。
