Hi,

I have a QDockWidget I want to hide/show with an action in the menu bar.

My code :

Code: Select all

QAction* dockInformations = this->dockinfo->toggleViewAction();
dockInformations->setText(i18nc("@dockwidget informations","Informations"));
dockInformations->setIcon(KIcon("mail-task"));
actionCollection()->addAction("dockInformations", dockInformations);

My apps.rc :

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE kpartgui SYSTEM "kpartgui.dtd">
<gui name="fusible" version="1">
   <MenuBar>
      ...
      <Menu name="settings" >
         <Action name="dockInformations" />
      </Menu>
   </MenuBar>
   <ToolBar name="mainToolBar" >
      ...
   </ToolBar>
</gui>

When I compile and execute, there is no action in my menu and I have the following warning :

Code: Select all

Attempt to use QAction "dockInformations" with KXMLGUIFactory!

But this action is available in the toolbar actions collection, I can add it in the main toolbar.

Where is my error?

You need to use the KAction class in KDE applications, as QActions should not be used. This is because QActions cannot be used in the shortcut dialog.

Thanks but how can I convert a QAction* to KAction*? There is no constructor or function for that.
When I write:

Code: Select all

QAction* dockInformations = (KAction*)this->dockinfo->toggleViewAction();

I have the same problem.

You will need to manually construct a KAction which has the appropriate icon, text, and slot connections and that to the collection manually.

Thank you, it works correctly.
I hoped to use toggleViewAction but it does not matter.
Final code is:

Code: Select all

   KAction* dockInformations = actionCollection()->addAction("show_dock_informations");
   dockInformations->setShortcut(QKeySequence(Qt::CTRL + Qt::Key_I));
   dockInformations->setText(i18n("Informations"));
   dockInformations->setIcon(KIcon("mail-task"));
   dockInformations->setCheckable(true);
   dockInformations->setChecked(this->dockinfo->isVisible());
   connect(dockInformations,SIGNAL(toggled(bool)), this->dockinfo, SLOT(setVisible(bool)));
