Splitlayout

Employment/Purpose

Splitlayout is a layout container, which is used to divide a component into two components.

These two components inside Splitlayout, the splitlayouts, are placed either horizontally or vertically by setting the orientation, and users can easily resize these two viewports by dragging the splitter bar. Also, like other ZK layout components, it supports hflex and vflex, indicating that users can divide the area into three or more spaces by putting the splitlayouts into the outer Splitlayout.

Comparing to Splitter, this component has several advantages:

  1. Splitter can only be used inside Hbox/ Vbox. Splitlayout has no such limitation.
  2. Hbox/Vbox are both rendered with HTML which is heavy for a browser. Splitlayout is rendered with div which is more light-weighted.

Example

ZKComRef Splitlayout Examples.PNG
    <splitlayout  vflex="1" hflex="1">
        <div sclass="area" hflex="1" vflex="1">
            <label value="Area 1"/>
        </div>
        <splitlayout vflex="1" hflex="1" orient="horizontal" >
            <div sclass="area" vflex="1" hflex="1">
                <label value="Area 2"/>
            </div>
            <div sclass="area" vflex="1"  hflex="2">
                <label value="Area 3"/>
            </div>
        </splitlayout>
    </splitlayout>

Properties and Features

Orientation

Default: vertical

Supported values: (default) “vertical” or “horizontal”.

The property specifies the layout orientation, determining how its two child containers are displayed in the component.

Collapse

The collapse property (Splitlayout.setCollapse(String)) specifies which side of the splitter is collapsed when its grippy (button) is clicked. If this property is not specified, the splitter will not cause a collapse.

Supported value: (default) “none”, “before” or "after". "before" means that the splitter in splitlayout would collapse to the left/top, and "after means splitter in splitlayout would collapse to the right/button.

Open

This method would not be able to work if the "collapse" attribute is not specified.

onOpen Event

When a splitlayout is collapsed or opened by a user, the onOpen event (OpenEvent) is sent to the application.

Widths and Heights

specify widths or heights with a list of numbers(in pixel) separated by a comma to denote the width/height of two areas in splitlayout. Notice that you should use them while using flex in the children component.

Specify Children Size in Proportion

Specify hflex/vflex on 2 children like:

        <splitlayout  vflex="1" >
            <div sclass="area" vflex="2">
                ...
            </div>
            <div sclass="area" vflex="3">
               ...
            </div>
        </splitlayout>

MinWidths and MinHeights

User setMinWidths(String minWidths) and setMinHeights(String minHeights) to sets the minimum widths/heights in the same format of setWidths/setHeights. When user drag the splitter, the two areas will not be smaller than the minWidths/minHeights.

Supported Events

Name
Event Type
onOpen
Event: OpenEvent

When a splitter is collapsed or opened by a user, the onOpen event is sent to the application.

onDivisionSize
Event: DivisionSizeEvent

Represents an event that indicates two inner size of splitlayout.
