How to open sub-menu on right hand side in rtl alignments?

I have a menu that consists of Items and sub-menus. the texts and titles of items should be shown from right to left. I achieved this by using LayoutMirroring.enabled = true.

    Menu {
        id: right_menu
        property var rtl: true;

        MenuItem {
            text: "گزینه ۱"
            LayoutMirroring.enabled: true
            LayoutMirroring.childrenInherit: true
        }

        Menu {
            title: "تنظیمات"

            MenuItem {
                LayoutMirroring.enabled: true
                LayoutMirroring.childrenInherit: true
                text: "گزینه ۱"
            }

            MenuItem {
                LayoutMirroring.enabled: true
                LayoutMirroring.childrenInherit: true
                text: "گزینه ۱"
            }
        }

        delegate: MenuItem {
            LayoutMirroring.enabled: true
            LayoutMirroring.childrenInherit: true
        }
    }

This is the output:

wrong output

However, this is not a valid output and I want to force the Menu to open subMenu on the right-hand side instead of left. this is the output I'm looking for:

expected output

How can I achieve this?

Solution

  • You can use the overlap property to shift the submenu over to the position you want.

    Note that if the position of the menu is too close to the left or right edge of the window, it will still open on the opposite side.

    Menu {
    id: right_menu
    property var rtl: true;

    MenuItem {
        text: "گزینه ۱"
        LayoutMirroring.enabled: true
        LayoutMirroring.childrenInherit: true
    }

    Menu {
        title: "تنظیمات"
        overlap: width * 2  // <<-- Shift the submenu over

        MenuItem {
            LayoutMirroring.enabled: true
            LayoutMirroring.childrenInherit: true
            text: "گزینه ۱"
        }

        MenuItem {
            LayoutMirroring.enabled: true
            LayoutMirroring.childrenInherit: true
            text: "گزینه ۱"
        }
    }

    delegate: MenuItem {
        LayoutMirroring.enabled: true
        LayoutMirroring.childrenInherit: true
    }
}
