Method Detail

setNativeControl

public void setNativeControl(boolean nativeControl)

Configures whether a native HTML5 control should be used.

When native, the new "number" input element, specified by HTML5 and when implemented by the browser, is used rather than the built-in element. The native control is styled by the browser (usually in sync with the OS) rather than through the theme chosen.

The default is false (as native support is now well implemented).

isNativeControl

public boolean isNativeControl()

Returns whether a native HTML5 control is used.

Taking into account the preference for a native control, configured using setNativeControl(), this method returns whether a native control is actually being used.

setPrefix

public void setPrefix(java.lang.CharSequence prefix)

Sets a prefix.

Option to set a prefix string shown in front of the value, e.g.:

 spinBox.setPrefix("$ ");
   
 

The default prefix is empty.

Note: Not supported by the native controls.

getPrefix

public WString getPrefix()

Returns the prefix.

See Also:

setPrefix(CharSequence prefix)

setSuffix

public void setSuffix(java.lang.CharSequence suffix)

Sets a suffix.

Option to set a suffix string shown to the right of the value, e.g.:

 spinBox.setSuffix(" crates");
   
 

The default suffix is empty.

Note: Not supported by the native controls.

getSuffix

public WString getSuffix()

Returns the suffix.

See Also:

setSuffix(CharSequence suffix)

setText

public void setText(java.lang.String text)

Description copied from class: WLineEdit

Sets the content of the line edit.

The default value is "".

Overrides:

setText in class WLineEdit

See Also:

WLineEdit.getText()

render

protected void render(java.util.EnumSet<RenderFlag> flags)

Overrides:

render in class WFormWidget

boxPadding

protected int boxPadding(Orientation orientation)

Description copied from class: WWidget

Returns the widget's built-in padding.

This is used by the layout managers to correct for a built-in padding which interferes with setting a widget's width (or height) to 100%.

A layout manager needs to set the width to 100% only for form widgets ( WTextArea, WLineEdit, WComboBox, etc...). Therefore, only for those widgets this needs to return the padding (the default implementation returns 0).

For form widgets, the padding depends on the specific browser/platform combination, unless an explicit padding is set for the widget.

When setting an explicit padding for the widget using a style class, you will want to reimplement this method to return this padding in case you want to set the widget inside a layout manager.

Overrides:

boxPadding in class WLineEdit

WWidget.boxBorder(Orientation orientation)
