    • setMaxLength

      public void setMaxLength(int length)
      Description copied from class: WLineEdit
      Specifies the maximum length of text that can be entered.

      A value <= 0 indicates that there is no limit.

      The default value is -1.

      Overrides:
      setMaxLength in class WLineEdit

    • setNativeControl

      public void setNativeControl(boolean nativeControl)
      Changes whether a native HTML5 control is used.

      When enabled the browser's native attribute for password input (<input type="password">) will be used instead of a validator.

      By default, this option is set to WWebWidget.isDefaultNativeControl(), which is false by default.

      See Also:

    • isNativeControl

      public boolean isNativeControl()
      Returns whether a native HTML5 control is used.

      See Also:

    • setTextVisible

      public void setTextVisible(boolean visible)
      Sets whether the password is shown in clear text.

      When enabled, the input changes its type from "password" to "text", revealing the content of the field.

      The default value is false.

      See Also:

    • isTextVisible

      public boolean isTextVisible()
      Returns whether the password is shown in clear text.

      See Also:

    • setRevealButtonEnabled

      public void setRevealButtonEnabled(boolean enabled)
      Shows or hides a button allowing the user to reveal the password.

      When enabled, a button is shown inside the line edit which toggles the visibility of the password. The toggle happens client-side, without a server round trip, and is reported back with textVisibilityChanged().

      The default value is false.

      Note: The button can only be activated with a pointer device. For a keyboard-accessible toggle, connect your own control to setTextVisible().

      Note: Hiding the button does not hide a password that is currently shown; use setTextVisible() for that.

      See Also:

    • isRevealButtonEnabled

      public boolean isRevealButtonEnabled()
      Returns whether the reveal button is shown.

      See Also:

    • textVisibilityChanged

      public JSignal1<Boolean> textVisibilityChanged()
      Signal emitted when the user toggles the text visibility.

      This is emitted when the visibility of the password is changed with the reveal button. The argument is whether the password is now shown in clear text.

      See Also:

    • setMinLength

      public void setMinLength(int length)

    • render

      protected void render(EnumSet<RenderFlag> flags)
      Description copied from class: WWidget
      Renders the widget.

      This function renders the widget (or an update for the widget), after this has been scheduled using scheduleRender().

      The default implementation will render the widget by serializing changes to JavaScript and HTML. You may want to reimplement this widget if you have been postponing some of the layout / rendering implementation until the latest moment possible. In that case you should make sure you call the base implementation however.

      render in class WLineEdit

      protected String getType()
      Overrides:
      getType in class WLineEdit
