a View to separate its subviews vertically by a movable bar; |
|
43 |
the size-ratios of the subviews can be changed by moving this bar. |
|
44 |
||
45 |
In order to correctly setup this kind of view, the subviews must |
|
46 |
be created with a relative origin & relative corner. |
|
47 |
The panel does not verify the relative subview bounds; |
|
48 |
therefore, it is your responsibility to set those relative sizes to fit |
|
49 |
according the orientation (see bad example below). |
|
50 |
||
51 |
The bar-handle is either an exposed knob (style == #motif) |
|
52 |
or the form defined in Scroller (style ~~ #motif) |
|
53 |
or nothing. |
|
54 |
||
55 |
Typically creation is done as: |
|
56 |
||
| 496 | 57 |
p := VariablePanel in:superView. |
58 |
p orientation:#vertical. |
|
| 295 | 59 |
|
| 496 | 60 |
v1 := <someViewClass> origin:0.0 @ 0.0 |
61 |
corner:1.0 @ 0.5 |
|
62 |
in:p. |
|
63 |
v2 := <someViewClass> origin:0.0 @ 0.5 |
|
64 |
corner:1.0 @ 0.8 |
|
65 |
in:p. |
|
66 |
v3 := <someViewClass> origin:0.0 @ 0.8 |
|
67 |
corner:1.0 @ 1.0 |
|
68 |
in:p. |
|
69 |
||
70 |
The two subclasses VariableHorizontalPanel and VariableVerticalPanel |
|
71 |
preset the orientation. They are a kept for backward compatibility |
|
72 |
(in previous versions, there used to be no common VariablePanel (super-) class). |
|
| 295 | 73 |
|
74 |
Notice: if it is required to insert a fixed-size view in the panel, |
|
75 |
use an extra view & insets, and place the subview into that extra view. |
|
76 |
||
77 |
