a View which arranges its child-views in a horizontal row.
|
|
|
39 |
All real work is done in PanelView - only the layout computation is
|
|
|
40 |
redefined here.
|
|
|
41 |
|
|
77
|
42 |
The layout is controlled the instance variables:
|
|
|
43 |
horizontalLayout and verticalLayout
|
|
127
|
44 |
in addition to
|
|
|
45 |
horizontalSpace and verticalSpace.
|
|
77
|
46 |
|
|
133
|
47 |
HorizontalSpace and verticalSpace control the spacing between elements;
|
|
|
48 |
they default to some 1mm.
|
|
|
49 |
|
|
62
|
50 |
The horizontal layout can be any of:
|
|
|
51 |
|
|
|
52 |
#left arrange elements at the left
|
|
|
53 |
#leftSpace arrange elements at the left, start with spacing
|
|
118
|
54 |
#fixLeft same as #left, but do not reduce spacing in case of no fit
|
|
|
55 |
#fixLeftSpace same as #leftSpace, but do not reduce spacing in case of no fit
|
|
62
|
56 |
#right arrange elements at the right
|
|
|
57 |
#rightSpace arrange elements at the right, start with spacing
|
|
|
58 |
#center arrange elements in the center
|
|
|
59 |
#spread spread elements evenly
|
|
77
|
60 |
#spreadSpace spread elements evenly with spacing at the ends
|
|
133
|
61 |
#fit like #spread, but resize elements for tight packing
|
|
|
62 |
#fitSpace like #fit, with additional spacing at the far ends
|
|
|
63 |
#leftFit like #left, but extend the last element to the right
|
|
|
64 |
#leftSpaceFit like #leftSpace, but extend the last element to the right
|
|
|
65 |
|
|
|
66 |
#leftMax like corresponding non-Max layouts,
|
|
|
67 |
#leftSpaceMax but resize all components to width of widest components
|
|
|
68 |
#rightMax
|
|
|
69 |
#rightSpaceMax
|
|
|
70 |
#centerMax
|
|
|
71 |
#spreadMax
|
|
|
72 |
#spreadSpaceMax
|
|
62
|
73 |
|
|
|
74 |
the vertical layout can be:
|
|
|
75 |
|
|
|
76 |
#top place element at the top
|
|
|
77 |
#topSpace place element at the top, offset by verticalSpace
|
|
|
78 |
#center place it horizontally centered
|
|
|
79 |
#bottom place it at the bottom
|
|
|
80 |
#bottomSpace place it at the bottom, offset by verticalSpace
|
|
|
81 |
#fit resize elements vertically to fit this panel
|
|
133
|
82 |
#fitSpace like #fit, but with spacing
|
|
|
83 |
|
|
|
84 |
#topMax like #top, but resize all views vertically to max height
|
|
|
85 |
#topSpaceMax like #topSpace, but resize all views vertically to max height
|
|
|
86 |
#bottomMax like #bottom, but resize all views vertically to max height
|
|
|
87 |
#bottomSpaceMax like #bottomSpace, but resize all views vertically to max height
|
|
|
88 |
#centerMax like #center, but resize all views vertically to max height
|
|
62
|
89 |
|
|
77
|
90 |
The defaults is #center for both directions.
|
|
62
|
91 |
The layout is changed by the messages #verticalLayout: and #horizontalLayout:.
|
|
|
92 |
For backward compatibility (to times, where only hLayout existed), the simple
|
|
133
|
93 |
#layout: does the same as #horizontalLayout:.
|
|
|
94 |
Do not use this old method; it will vanish and currently outpus a warning.
|
|
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
|
|
133
|
100 |
to size changes of its elements, and reorganize things.
|
|
127
|
101 |
|
|
118
|
102 |
By combining Horizontal- and VerticalPanels (i.e. place a hPanel into a
|
|
|
103 |
vPanel), most layouts should be implementable.
|
|
133
|
104 |
However, iff none of these layout/space combinations is exactly what you need
|
|
118
|
105 |
in your application, create a subclass, and redefine the setChildPositions
|
|
|
106 |
method there.
|
|
125
|
107 |
|
|
|
108 |
TODO: for completeness, support #fixRight, #fixRightSpace,
|
|
|
109 |
#rightFit, #rightSpaceFit layouts
|
|
127
|
110 |
|
|
|
111 |
CAVEAT: this class started with #left and no vertical alignments;
|
|
133
|
112 |
as time went by, more layouts were added (by users requests)
|
|
|
113 |
and noew, many layout combinations are possible.
|
|
|
114 |
Reflecting this, the setup should be changed to use different selectors
|
|
|
115 |
for space-on/off, max-resize and alignment
|
|
127
|
116 |
(i.e. having more and more layout symbols makes things a bit confusing ...)

"

|

|
122 |
These examples show the effect of various horizontalLayout and
|
|
|
123 |
verticalLayout settings. Try them all. Especially, notice the
|
|
|
124 |
differences between the xxx and xxxSpace layouts and the effect of
|
|
|
125 |
setting different values for the spacing.
|
|
|
126 |
Try resizing the view and see how the elements get rearranged.
|
|
|
127 |

Most of the examples below place 3 buttons onto a panel; Of course,
|
|
|
129 |
you can put any other view into a panel ... the last examples show this.
