Custom behavior for Drawer

[Camilo del Real]

Hi, I have an application with a StackView as main layout and a Drawer. I want the Drawer only be accessed when the StackView has only one component. According to QtQuick Controls 2's documentation I can do it setting the property dragMargin of Drawer to 0 or a less value. So I did this

Drawer {
id: drawer
dragMargin: rootLayout.depth > 1 ? 0 : Qt.styleHints.startDragDistance
...
}

StackView {
id: rootLayout
...
}

But does not work at all, because you can access dragging your finger from the edge of the phone. The only thing that achievement is to drastically reduce the area to get the Drawer.
I appretiate the help, because I have a Page that insert into the StackView containing a SwipeView with content close to the edges and has conflicts with the Drawer that is not disabled. I tried setting 0 and -10 to dragMargin, but noting

Hi! How about disabling the Drawer?

Drawer {
   id: drawer
   enabled: rootLayout.depth == 0
   onEnabledChanged: dragMargin = enabled ? Qt.styleHints.startDragDistance : 0
}

The documentation and the compiler say that the property does not exist, which is strange because all components have always brought this property

@Camilo-del-Real Oh, sry. Then maybe visible should do the same.

If I use

Drawer {
visible: appContentManager.depth == 1
onVisibleChanged: dragMargin = visible ? Qt.styleHints.startDragDistance : 0
}

the drawer is always show at start up (it is not something to be) and with the treatment of onVisibleChanged the Drawer always has 0 in dragMargin when is hidden, which causes only be difficult to show it with draggind

If it's possible to drag a drawer open when it has drag margin set to 0, then please report a bug with appropriate details about the platform and device: https://bugreports.qt.io

Well, I found a temporary solution while the original idea is fixed with dragMargin. Making the width is 0 can disable the Drawer, but only with the combination of width and dragMargin, if only use width, is still possible show a Drawer (an empty drawer)

Drawer {
        dragMargin: appContentManager.depth > 1 ? 0 : Qt.styleHints.startDragDistance
        width: appContentManager.depth > 1 ? 0 : Math.min(appRoot.width, appRoot.height) / 3 * 2
}

I also report the bug
