It is the same as AbstractComponent.getParent().
public void setColumnshide(boolean columnshide)
Note that it is only applied when getMenupopup() is auto.
public boolean isColumnshide()
Default: true.
public void setColumnsgroup(boolean columnsgroup)
Note that it is only applied when getMenupopup() is auto.
public boolean isColumnsgroup()
Default: true.
public java.lang.String getMenupopup()
Menupopup) that should appear
when the user clicks on the element.
Default: none (a default menupopup).
public void setMenupopup(java.lang.String mpop)
Menupopup) that should appear
when the user clicks on the element of each column.
An onOpen event is sent to the popup menu if it is going to appear. Therefore, developers can manipulate it dynamically (perhaps based on OpenEvent.getReference) by listening to the onOpen event.
Note: To simplify the use, it ignores the ID space when locating the component at the client. In other words, it searches for the first component with the specified ID, no matter it is in the same ID space or not.
If there are two components with the same ID (of course, in
different ID spaces), you can specify the UUID with the following
format:
uuid(comp_uuid)
mpop - an ID of the menupopup component, "none", or "auto".
"none" is assumed by default, "auto" means the menupopup component is
created automatically.setMenupopup(String)protected void renderProperties(ContentRenderer renderer) throws java.io.IOException

Grid and Column instead.HtmlBasedComponentsetWidth in class HtmlBasedComponentHtmlBasedComponent.setWidthDirectly(java.lang.String),
AbstractComponent.disableClientUpdate(boolean)public void setHflex(java.lang.String flex)
Grid and Column instead.HtmlBasedComponentNumber 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.
setHflex in class HtmlBasedComponentflex - horizontal flex hint of this component.HtmlBasedComponent.setVflex(java.lang.String),
HtmlBasedComponent.getHflex()public java.lang.String getZclass()
HtmlBasedComponentAbstractComponent.getMold()).
Default: null (the default value depends on element).
HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style
of a component. In other words, the default style of a component
is associated with the default value of HtmlBasedComponent.getZclass().
Once it is changed, the default style won't be applied at all.
If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String)
instead.
