a View which arranges its child-views in a vertical column.
|
|
63
|
54 |
All real work is done in PanelView - except the layout computation is
|
|
38
|
55 |
redefined here.
|
|
|
56 |
|
|
127
|
57 |
The layout is controlled by the instance variables:
|
|
77
|
58 |
horizontalLayout and verticalLayout
|
|
127
|
59 |
in addition to
|
|
|
60 |
horizontalSpace and verticalSpace.
|
|
77
|
61 |
|
|
63
|
62 |
The vertical layout can be any of:
|
|
|
63 |
|
|
|
64 |
#top arrange elements at the top
|
|
|
65 |
#topSpace arrange elements at the top, start with spacing
|
|
|
66 |
#bottom arrange elements at the bottom
|
|
|
67 |
#bottomSpace arrange elements at the bottom, start with spacing
|
|
127
|
68 |
#center arrange elements in the center; ignore verticalSpace
|
|
|
69 |
#spread spread elements evenly; ignore verticalSpace
|
|
|
70 |
#spreadSpace spread elements evenly with spacing at ends; ignore verticalSpace
|
|
|
71 |
#fit like spread, but resize elements for tight packing; ignore verticalSpace
|
|
|
72 |
#fitSpace like fit, with spacing; ignore verticalSpace
|
|
63
|
73 |
|
|
|
74 |
the horizontal layout can be:
|
|
|
75 |
|
|
|
76 |
#left place element at the left
|
|
|
77 |
#leftSpace place element at the left, offset by horizontalSpace
|
|
127
|
78 |
#center place elements horizontally centered; ignore horizontalSpace
|
|
63
|
79 |
#right place it at the right
|
|
|
80 |
#rightSpace place it at the right, offset by horizontalSpace
|
|
127
|
81 |
#fit resize elements horizontally to fit this panel; ignore horizontalSpace
|
|
|
82 |
#fitSpace like fit, but add spacing; ignore horizontalSpace
|
|
|
83 |
|
|
|
84 |
#leftMax like #left, but resize elements to max of them
|
|
|
85 |
#leftSpaceMax like #leftSpace, but resize elements
|
|
|
86 |
#centerMax like #center, but resize elements
|
|
|
87 |
#rightMax like #right, but resize elements to max of them
|
|
|
88 |
#rightSpaceMax like #rightSpace, but resize elements
|
|
63
|
89 |
|
|
77
|
90 |
The defaults is #center for both directions.
|
|
127
|
91 |
|
|
63
|
92 |
The layout is changed by the messages #verticalLayout: and #horizontalLayout:.
|
|
|
93 |
For backward compatibility (to times, where only vLayout existed), the simple
|
|
|
94 |
#layout: does the same as #verticalLayout:. Do not use this old method.
|
|
77
|
95 |
|
|
127
|
96 |
The panel assumes, that the elements do not resize themselfes, after it
|
|
|
97 |
became visible. This is not true for all widgets (buttons or labels may
|
|
|
98 |
like to change). If you have changing elements, tell this to the panel
|
|
|
99 |
with 'aPanel elementsChangeSize:true'. In that case, the panel will react
|
|
|
100 |
to size changes, and reorganize things.
|
|
|
101 |
|
|
77
|
102 |
If none of these layout/space combinations is exactly what you need in
|
|
|
103 |
your application, create a subclass, and redefine the setChildPositions method.
|
|
127
|
104 |
|
|
|
105 |
CAVEAT: this class started with #top and no horizontal alignments;
|
|
|
106 |
as time went by, more layouts were added and the setup should be changed
|
|
|
107 |
to use different selectors for space, max-resize and alignment
|
|
|
108 |
(i.e. having more and more layout symbols makes things a bit confusing ...)

These examples demonstrate the effect of different layout
|
|
|
115 |
settings.
|
|
|
116 |
You should try more examples, combining spacing and different
|
|
|
117 |
verticalLayout:/horizontalLayout: combinations.
