this class implements modal boxes; ModalBoxes are different from
|
|
81
|
52 |
others, in that they take control over the current topview, until
|
|
|
53 |
all processing is done (i.e. the currently active topview and all of
|
|
|
54 |
its subviews will not handle user events while the box is active).
|
|
89
|
55 |
|
|
|
56 |
ModalBoxes are either implemented as transient windows
|
|
|
57 |
(if UseTransientViews := true) or as override redirect views.
|
|
|
58 |
Some window managers have problems with either; so you may want to
|
|
|
59 |
change the default setting from your display.rc file.
