61 | \brief The Q3GroupBox widget provides a group box frame with a title.
|
---|
62 |
|
---|
63 | \compat
|
---|
64 |
|
---|
65 | A group box provides a frame, a title and a keyboard shortcut, and
|
---|
66 | displays various other widgets inside itself. The title is on top,
|
---|
67 | the keyboard shortcut moves keyboard focus to one of the group
|
---|
68 | box's child widgets, and the child widgets are usually laid out
|
---|
69 | horizontally (or vertically) inside the frame.
|
---|
70 |
|
---|
71 | The simplest way to use it is to create a group box with the
|
---|
72 | desired number of columns (or rows) and orientation, and then just
|
---|
73 | create widgets with the group box as parent.
|
---|
74 |
|
---|
75 | It is also possible to change the orientation() and number of
|
---|
76 | columns() after construction, or to ignore all the automatic
|
---|
77 | layout support and manage the layout yourself. You can add 'empty'
|
---|
78 | spaces to the group box with addSpace().
|
---|
79 |
|
---|
80 | Q3GroupBox also lets you set the title() (normally set in the
|
---|
81 | constructor) and the title's alignment().
|
---|
82 |
|
---|
83 | You can change the spacing used by the group box with
|
---|
84 | setInsideMargin() and setInsideSpacing(). To minimize space
|
---|
85 | consumption, you can remove the right, left and bottom edges of
|
---|
86 | the frame with setFlat().
