      • getOrient

        public java.lang.String getOrient()
        Returns the orient.

        Default: "horizontal".

               throws WrongValueException
        Sets the orient.

        WrongValueException

      • getItems

        public java.util.List<Radio> getItems()
        Returns a readonly list of Radio. Note: any update to the list won't affect the state of this radio group.
        Since:
        5.0.4

      • getItemAtIndex

        public Radio getItemAtIndex​(int index)
        Returns the radio button at the specified index.

      • getItemCount

        public int getItemCount()
        Returns the number of radio buttons in this group.

      • getSelectedIndex

        public int getSelectedIndex()
        Returns the index of the selected radio button (-1 if no one is selected). Note: The index of the external radio button could be unintuitive since radio group always count descendant radio before external radio.

      • setSelectedIndex

        public void setSelectedIndex​(int jsel)
        Deselects all of the currently selected radio button and selects the radio button with the given index.

      • getSelectedItem

        public Radio getSelectedItem()
        Returns the selected radio button.

      • setSelectedItem

        public void setSelectedItem​(Radio item)
        Deselects all of the currently selected radio buttons and selects the given radio button.

      • appendItem

        public Radio appendItem​(java.lang.String label,
                        java.lang.String value)
        Appends a radio button.

      • removeItemAt

        public Radio removeItemAt​(int index)
        Removes the child radio button in the radio group at the given index.
        Returns:
        the removed radio button.

      • getName

        public java.lang.String getName()
        Returns the name of this group of radio buttons. All child radio buttons shared the same name (Radio.getName()).

        Default: automatically generated a unique name

        Don't use this method if your application is purely based on ZK's event-driven model.

      • setName

        public void setName​(java.lang.String name)
        Sets the name of this group of radio buttons. All child radio buttons shared the same name (Radio.getName()).

        Don't use this method if your application is purely based on ZK's event-driven model.

      • isDisabled

        public boolean isDisabled()
        Returns whether it is disabled.

        Default: false.

        Specified by:
        isDisabled in interface Disable
        Since:
        9.6.0

      • setDisabled

        public void setDisabled​(boolean disabled)
        Sets whether the radiogroup is disabled. All the radios belong to this radiogroup will be set to disabled or not disabled as well. Notice: Once a radio is added to a disabled radiogroup (including external radio), the radio will be set to disabled too.
        Specified by:
        setDisabled in interface Disable
        Parameters:
        disabled - whether the radiogroup is disabled
        Since:
        9.6.0

      • getModel

        public <T> ListModel<T> getModel()
        Returns the list model associated with this radiogroup, or null if this radiogroup is not associated with any list data model.
        Since:
        6.0.0

      • setModel

        public void setModel​(ListModel<?> model)
        Sets the list model associated with this radiogroup. If a non-null model is assigned, no matter whether it is the same as the previous, it will always cause re-render.
        Parameters:
        model - the list model to associate, or null to dis-associate any previous model.
        Throws:
        UiException - if failed to initialize with the model
        Since:
        6.0.0

      • onInitRender

        public void onInitRender​(Event data)
        For model rendering

        data -

      • getRadioRenderer

        public <T> RadioRenderer<T> getRadioRenderer()
        Returns the renderer to render each radio, or null if the default renderer is used.
        Since:
        6.0.0

      • setRadioRenderer

        public void setRadioRenderer​(RadioRenderer<?> renderer)
        Sets the renderer which is used to render each row if getModel() is not null.

        Note: changing a render will not cause the radiogroup to re-render. If you want it to re-render, you could assign the same model again (i.e., setModel(getModel())), or fire an ListDataEvent event.

        Parameters:
        renderer - the renderer, or null to use the default.
        Throws:
        UiException - if failed to initialize with the model
        Since:
        6.0.0
