Created custom designer plugin similar to Container Extension Example. After some modifications with QDesignerCustomWidgetInterface, QDesignerContainerExtension and QExtensionFactory classes and adding following methods to my container:
Q_OBJECT
Q_PROPERTY(int currentIndex READ currentIndex WRITE setCurrentIndex)
Q_PROPERTY(QString pageTitle READ pageTitle WRITE setPageTitle STORED false)
public:
WidgetBox(QWidget *parent = 0);
int count() const { return mTreeWidget->topLevelItemCount(); }
QWidget* widget(int index) const;
QString pageTitle() const;
public slots:
void setCurrentIndex(int index);
void addPage(QWidget *widget);
void insertPage(int index, QWidget *widget);
void removePage(int index);
int currentIndex() const { return mTreeWidget->currentIndex().row(); }
void setPageTitle(QString const &newTitle);
protected:
QTreeWidgetItem * addCategory(QString pageName);
QTreeWidgetItem * insertCategory(int index, QString pageName);
PageButton *categoryButton(int index) const;
void createContainerWidget(QTreeWidgetItem* page, QWidget *widget);
void createCategoryButton(QTreeWidgetItem* page, QString pageName);
signals:
void currentIndexChanged(int index);
void pageTitleChanged(const QString &title);
Qt designer started to crash on start with my plugin. Any way do debug plugin (extension) and found the cause? Plugin build in release mode with same Qt and VS C++ versions as Qt Designer and Creator - Based on Qt 5.5.1 (MSVC 2013, 32 bit).
P.S. So method is following: commented out extension and factory classes - still crashes, sequentaly commented/uncommented methods in my widget class: problem appears in
Q_PROPERTY(QString pageTitle READ pageTitle WRITE setPageTitle STORED false)
and methods pageTitle and setPageTitle for current page when no pages available. Need think what to set/output here when no pages were added. Or add at least 1 page by default.
Now Qt Designer crashes on adding widget to a form. Will continue searching the cause.
