Fix popup dialogs and other stuff
Replaces !312 (closed)
DownloadItemsSheet: Wrap the file names of entries instead of eliding
We are not short on space here, and not having any other means to read the whole string (like tooltips on hover) is kinda hostile toward user.
DownloadItemsSheet: Port from OverlaySheet to Kirigami.Dialog for file selection dialog
OverlaySheet acts weird when it's opened inside a ScrollView.
Dialog just opens on top of the view like OverlaySheet, without the issues, while looking mostly similar.
Don't show close button anymore. There's already a standard QQC2.Dialog.Close button provided by the Dialog type now.
Note from ratijas: Unlike the super-magical OverlaySheet, the Dialog
needs clip: true to be set on the ListView, otherwise the content
will be visible out of bounds when scrolled away.
Explicitly set QQC2.Overlay.overlay as a parent for popups
Because that's how popups work in QtQuick.Controls. And that's what goes wrong
in Kirigami with its "implicit" bindings directly inside Dialog and
OverlaySheet types. Because QQC2.Overlay.overlay has to be queried on a real
Item which already belongs to some window; if you query it on a Popup itself
you'd get a null overlay, but the Popup are usually declared as child objects
of some other Item in which case said Item would become not only
QObject::parent but also a visual Item parent of a Popup, thus accidentally
making QQC2.Overlay.overlay work -- only to immediately reassign parent
Item to an overlay itself. This sounds like a rather unintentional loophole
rather than a well-thought architectural design, so let's avoid that pattern,
and just bind a parent normally.
QuestionAsker: Remove broken sizing bindings
They were completely backwards: calculating implicit size form an
explicit one, and referencing some non-existing view id. The implicit
size provided by a QQC2 style implementation should be good enough, and
the ColumnLayout's content has some limits on maximum width.
Also, center in parent because a dialog can not meaningfully refer to a QQC2.Overlay attached property from within itself.
Fix the "Use" label on certain delegates
