Grails ZK UI Plugin 0.4 - Reference Documentation

The hlayout component is a simple horizontal oriented layout. Each component placed in the hlayout will be placed horizontally in a row.Notice that hlayout and vlayout do not support splitter. If you need it, please use Hbox and Vbox instead.

<z:vlayout>
    <z:button label="Button 1"/>
    <z:button label="Button 2"/>
</z:vlayout>
<z:hlayout>
    <z:button label="Button 3"/>
    <z:button label="Button 4"/>
</z:hlayout>

Description

Attributes

spacing (optional) - Sets the spacing between adjacent children. see more

class (optional) - Sets the CSS class. This method is a bit confused with Java's class, but we provide it for XUL compatibility. The same as setSclass(java.lang.String). see more

left (optional) - Sets the left position. If you want to specify right, use setStyle(java.lang.String) instead. For example, setStyle("right: 0px"); see more

top (optional) - Sets the top position. If you want to specify bottom, use setStyle(java.lang.String) instead. For example, setStyle("bottom: 0px"); see more

zIndex (optional) - Sets the Z index. see more

zindex (optional) - Sets the Z index. see more

height (optional) - Sets the height. If null, the best fit is used. see more

tooltiptext (optional) - Sets the text as the tooltip. see more

zclass (optional) - Sets the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (@{link #getMold}). see more

sclass (optional) - Sets the CSS class. see more

draggable (optional) - Sets "true" or "false" to denote whether a component is draggable, or an identifier of a draggable type of objects. The simplest way to make a component draggable is to set this attribute to true. To disable it, set this to false. If there are several types of draggable objects, you could assign an identifier for each type of draggable object. The identifier could be anything but empty. see more

droppable (optional) - Sets "true" or "false" to denote whether a component is droppable, or a list of identifiers of draggable types of objects that could be droped to this component. The simplest way to make a component droppable is to set this attribute to true. To disable it, set this to false. If there are several types of draggable objects and this component accepts only some of them, you could assign a list of identifiers that this component accepts, separated by comma. For example, if this component accepts dg1 and dg2, then assign "dg1, dg2" to this attribute. see more

focus (optional) - Sets focus to this element. It is same as focus(), but used to allow ZUML to set focus to particular component. <textbox focus="true"/> see more

renderdefer (optional) - Sets the number of milliseconds before rendering this component at the client. Default: -1 (don't wait). This method is useful if you have a sophiscated page that takes long to render at a slow client. You can specify a non-negative value as the render-defer delay such that the other part of the UI can appear earlier. The styling of the render-deferred widget is controlled by a CSS class called z-renderdefer. Notice that it has no effect if the component has been rendered at the client. see more

vflex (optional) - Sets vertical flexibility hint of this component. Number flex indicates how this component's container distributes remaining empty space among its children vertically. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios. Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1. Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components. see more

hflex (optional) - Sets horizontal flex hint of this component. Number flex indicates how this component's container distributes remaining empty space among its children horizontally. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios. Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1. Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components. see more

width (optional) - Sets the width. If null, the best fit is used. see more

style (optional) - Sets the CSS style. see more

action (optional) - Sets the client-side action (CSA). Default: null (no CSA at all) The format: action1: action-effect1; action2: action-effect2 Currently, only two actions are show and hide. They are called when the widget is becoming visible (show) and invisible (hide). The action effect (action-effect1) is the name of a method defined in zk.Actions, such as show: slideDown; hide: slideUp You could specify the effects as follows: show: slideDown({duration:1000}) Security Tips: the action is not encoded and it is OK to embed JavaScript, so, if you want to allow users to specify the action, you have to encode it. Note for developers upgraded from ZK 3: CSA's format is different and limited. In additions, it is part of HtmlBasedComponent. see more

id (optional) - Description copied from interface: Component Sets the ID. The scope of uniqueness depends on whether this component is a root component. Refer to Component.getId() for more details. Default: "" (an empty string; it means no ID at all). see more

mold (optional) - Description copied from interface: Component Sets the mold to render this component. see more

widgetClass (optional) - Description copied from interface: Component Sets the widget class (aka., the widget type). The widget class is a JavaScript class, including the package name. For example, "zul.wnd.Window". see more

stubonly (optional) - Description copied from interface: Component Sets whether this component is stub-only. By stub-only, we mean we don't need to maintain the states of the component at the server side. Default: "inherit" (i.e., the same as the parent's stub-only, and "false" is assumed if none of parents is specified with stub-only). If a component is set to stub-only, the application running at the server shall not access it anymore after renderred to the client. The ZK loader will try to minimize the memory footprint by merging stub-only components and replacing with light-weight components. However, the event listeners and handlers are preserved, so they will be invoked if the corresponding event is received. Since the original component is gone, the event is the more generic format: an instance of Event (rather than MouseEvent or others). If a component is stub-only, the application usually access it only at the client since all widgets are preserved at the client (so are events). This method is available only for ZK EE. see more

definition (optional) - Description copied from interface: ComponentCtrl Sets the component definition by specifing the name. see more

visible (optional) - Description copied from interface: Component Sets whether this component is visible. see more
