GoldenLayout

[ since 8.6.0 ]

Employment/Purpose

GoldenLayout is a layout container which layouts panels as docker type, and is used to represent GoldenLayout. There area two components nested for this Layout, GoldenLayout and GoldenPanel. GoldenLayout is the parent component, and it's children component can only be GoldenPanel.

A GoldenLayout could be nested to another GoldenLayout (actually, almost all kinds of components) to form a complicated layout.

Example

ZKCompRef GoldenLayout.png

    <goldenlayout vflex="1" hflex="1">
        <attribute name="areas">
            A A B
            A A B
            C C D
        </attribute>
        <goldenpanel area="A" title="Panel A">
            <window vflex="1" title="Window inside GoldenPanel A" border="normal"/>
        </goldenpanel>
        <goldenpanel area="B" title="Panel B">
            <button label="Button inside GoldenPanel B"/>
        </goldenpanel>
        <goldenpanel area="C" title="Panel C">
            <vlayout>
                SplitLayout inside GoldenPanel C
                <splitlayout hflex="1" height="500px">
                    <tbeditor vflex="1"/>
                    <window border="normal" title="Window" vflex="1"/>
                </splitlayout>
            </vlayout>
        </goldenpanel>
        <goldenpanel area="D" title="Panel D">
            <vlayout>
                Rating inside GoldenPanel D
                <rating max="10" rating="8"/>
            </vlayout>
        </goldenpanel>
    </goldenlayout>

Properties and Features

The goldenLayout is layouted as docker type, and is usually construct with a tree structure, which is hard to layout in zul. ZK change the structure for initial rendering to a one layer design. All the GoldenPanels are in one layer inside GoldenLayout, and the panels layout pattern will be specified by the areas attribute of GoldenLayout and area attribute of GoldenPanel. The order added to the GoldenLayout only represents the stacking order if they are stacked together in the same area.

Areas

The areas attribute is a sugar for initializing the layout. In the example code above, we have the areas in line 2 specified as

A A B

A A B

C C D

and it's possible to be divide in two ways, vertical or horizontal. Note that, A A B will result as hflex A is 2 and hflex B is 1. Same with vflex. But if hflex or vflex attribute is specified on the GoldenPanel which area is A, it overrides the flex size calculated by the GoldenLayout's areas attribute.


Orient

The orient indicates the initial splitting orientation if you layout it by the area attribute. Supported value: (default) “vertical” or “horizontal”.


Adding GoldenPanels

By user's drag drop, the GoldenPanels are usually dropped to a region like north, east, south, west and stack of a GoldenPanel. So we provide some GoldenPanel adding APIs to simulate these actions. Please refer to the addPanel APIs like GoldenLayout.addPanel(GoldenPanel, GoldenPanel, String) in GoldenLayout.
