Drop down menu in @toolbar

alexandrePhoton

Hello,

I am trying to create a menu in the toolbar in the style of the Ruler or the Technology selector.
A action trig and a drop down menu together. I manage to do the two separately but not together.
I have no idea how to bin the action with the menu. Anybody did this before ?

Hi, Alex!

I think you need to call QToolButton::setDefaultAction.

Hi sir,
Can you get us more detail sample code for that ?
I want to create a menu buttom in Klayout to call my Ruby/DRC code.
But , I don't know how to call QToolButtom.. in my code...
Thanks.

@jiunnweiyeh KLayout employs a menu abstraction instead of direct Qt element access. The reason is that I cannot ensure compatibility of the Widget hierarchy across multiple releases.

The involved classes here are AbstractMenu and Action:

Here is an example:

mw = RBA::MainWindow::instance

# create a toolbar submenu
mw.menu.insert_menu("@toolbar.end", "toolbar_submenu", "Submenu")

# fill the menu with three items
(1..3).each do |item|

  item_name = "item#{item}"

  # create an Action object to bind the item to
  action = RBA::Action::new
  action.title = "Item #{item}"
  action.on_triggered do
    # implement the action here ...
    RBA::MessageBox::info("Info", "Item #{item} clicked!", RBA::MessageBox::Ok)
  end

  # Insert the action as an item into the menu
  mw.menu.insert_item("@toolbar.toolbar_submenu.end", item_name, action)

end

Hello Matthias,

Ruby is cool ! But I am still far away from building it as a master. I start to do something by using above submenu code,
and wonder if I can get the submenu just launching Klayout, without running the code again ?

Maybe there is some magic skill here ?

Thanks
Vincent

HI Vincent Lin,

you can enabling "run on startup" from the setup.
