Constructor Detail

Tab

public Tab()

Constructs a new object in its default state.

Tab

public Tab(String label)

Constructs a new object with the given label.

Parameters:

label - the label to display

Tab

public Tab(Component... components)

Constructs a new object with child components.

Parameters:

components - the child components

Method Detail

getLabel

public final String getLabel()

Gets the label of this tab.

Returns:

the label

setLabel

public final void setLabel(String label)

Sets the label of this tab.

Parameters:

label - the label to display

setFlexGrow

public void setFlexGrow(double flexGrow)

Sets the flex grow property of this tab. The flex grow property specifies what amount of the available space inside the layout the component should take up, proportionally to the other components.

For example, if all components have a flex grow property value set to 1, the remaining space in the layout will be distributed equally to all components inside the layout. If you set a flex grow property of one component to 2, that component will take twice the available space as the other components, and so on.

Setting to flex grow property value 0 disables the expansion of the component. Negative values are not allowed.

Parameters:

flexGrow - the proportion of the available space the tab should take up

getFlexGrow

public double getFlexGrow()

Gets the flex grow property of this tab.

Returns:

the flex grow property, or 0 if none was set

setSelected

public void setSelected(boolean selected)

Description copied from class: GeneratedVaadinTab

Description copied from corresponding location in WebComponent:

If true, the item is in selected state.

Overrides:

setSelected in class GeneratedVaadinTab<Tab>

Parameters:

selected - the boolean value to set

isSelected

public boolean isSelected()

If true, the item is in selected state.

This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.

If a Tab instance is used inside Tabs component then selected state is updated based on currently selected tab. So the value is the same as Tabs.getSelectedTab().

Returns:

the selected property from the webcomponent

Tabs.getSelectedTab()

toString

public String toString()

Overrides:

toString in class Object
