withIcon

public UIForLabel<L> withIcon(Icon icon)

Use this to set the icon for the wrapped JLabel. This is in essence a convenience method to avoid peeking into this builder like so:

     UI.label("Something")
         .peek( label -> label.setIcon(...) );
  

Parameters:

icon - The Icon which should be displayed on the label.

Returns:

This very builder to allow for method chaining.

withIcon

public UIForLabel<L> withIcon(IconDeclaration icon)

Use this to set the icon for the wrapped JLabel based on the provided IconDeclaration.

An IconDeclaration should be preferred over the Icon class as part of a view model, because it is a lightweight value object that merely models the resource location of the icon even if it is not yet loaded or even does not exist at all.

Parameters:

icon - The IconDeclaration which should be displayed on the label.

Returns:

This very builder to allow for method chaining.

withIcon

public UIForLabel<L> withIcon(sprouts.Val<IconDeclaration> icon)

Use this to dynamically set the icon property for the wrapped JLabel. When the icon wrapped by the provided property changes, then so does the icon of this label.

But note that you may not use the Icon or ImageIcon classes directly, instead you must use implementations of the IconDeclaration interface, which merely models the resource location of the icon, but does not load the whole icon itself.

The reason for this distinction is the fact that traditional Swing icons are heavy objects whose loading may or may not succeed, and so they are not suitable for direct use in a property as part of your view model. Instead, you should use the IconDeclaration interface, which is a lightweight value object that merely models the resource location of the icon even if it is not yet loaded or even does not exist at all.

This is especially useful in case of unit tests for you view model, where the icon may not be available at all, but you still want to test the behaviour of your view model.

Parameters:

icon - The Icon property which should be displayed on the label.

Returns:

This very builder to allow for method chaining.

Throws:

IllegalArgumentException - if icon is null.

withFontSize

public UIForLabel<L> withFontSize(int size)

Use this to set the size of the font of the wrapped JLabel.

Parameters:

size - The size of the font which should be displayed on the label.

Returns:

This very builder to allow for method chaining.

withFontSize

public UIForLabel<L> withFontSize(sprouts.Val<Integer> size)

Use this to dynamically set the size of the font of the wrapped JLabel through the provided view model property. When the integer wrapped by the provided property changes, then so does the font size of this label.

Parameters:

size - The size property of the font which should be displayed on the label.

Returns:

This very builder to allow for method chaining.

Throws:

IllegalArgumentException - if size is null.

withFont

public final UIForLabel<L> withFont(Font font)

Use this to set the font of the wrapped JLabel.

Parameters:

font - The font of the text which should be displayed on the label.

Returns:

This builder instance, to allow for method chaining.

Throws:

IllegalArgumentException - if font is null.

withFont

public final UIForLabel<L> withFont(sprouts.Val<Font> font)

Use this to dynamically set the font of the wrapped JLabel through the provided view model property. When the font wrapped by the provided property changes, then so does the font of this label.

Parameters:

font - The font property of the text which should be displayed on the label.

Returns:

This builder instance, to allow for method chaining.

Throws:

IllegalArgumentException - if font is null.

IllegalArgumentException - if font is a property which can wrap null.
