Bug ID: 465925
Summary: DialogButtonBox does not respect explicit width
constraint, overflows, and does not scroll
Classification: Frameworks and Libraries
Product: frameworks-qqc2-desktop-style
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED

SUMMARY
With current implementation[1] of Kirigami.Dialog, dialog footer's implicit
size is not honored, so it's possible to get a dialog smaller than what footer
wanted to be. Regardless of that Kirigami issue, Kirigami.Dialog is a subtype
of QQC2 Templates Popup, so it's constrained by its parent window size minus
margins, so dialog can't count on its implicit size being honored anyway.
The problem is, qqc2-desktop-style implementation of DialogButtonBox is not
adaptive to explicit size constraints:
1. It does not clip its buttons, so they overflow;
2. They don't scroll horizontally, even though they are in a ListView;
3. The less space you give to DialogButtonBox to accommodate itself, the more
it moves to the left. o_O
STEPS TO REPRODUCE
1. Run snippet[2] in qmlscene
2. Resize window (shrink, stretch)
OBSERVED RESULT
a) Without Kirigami patch, Dialog is zero-width. It does not respect footer
size, so all its DialogButtonBox buttons are invisible. With Kirigami patch,
only right dialog's "Yahaha" button is visible which does not belong to
DialogButtonBox anyway (added through customFooterActions).
b) DialogButtonBox moves to the left when there is no enough space for it, i.e.
width < implicitWidth.
EXPECTED RESULT
DialogButtonBox should not move to the left, leaving empty space on the right.
DialogButtonBox should react "properly" to width constraints, either wrapping
in multiple lines, or scrolling horizontally, or both.
