Class comlexMenu is an applet that has an associated frame that can be displayed or hidden fashion to The frame contains a menu bar containing two menus called Colours and Font respectively.
The Colours menu allows the user to select the frame�s background colour from the following: white, light grey and yellow. The default colour is white. The following text os displayed, in black, in the middle of a label object: �A frame demonstration�.
The Font menu allows the user to select from the following font sizes and updates the text in the label object accordingly: 10, 12, 14, 16, 18 points. The default size is 12 points. An additional item called Message, allows the user to change the message displayed in the label. When selected it causes a modal dialog box, similar to that in class SimpleDialog, to appear. The dialog box contains a text field, width 30 columns, which displays the message �Enter your new message�, and a button marked �OK�. The user then enters a new message and presses the OK button whereupon the dialog box disappers and the new message appears in the frame�s label. Submit PDL designs for class ComplexMenu�s methods together with a Java implementation suitably indented and commented.
You are to implement an applet, called FileName with the user interface shown in the diagram. The user inputs a file name by clicking on the appropriate buttons. As each character is input it is displayed in the upper text field.
In addition to these buttons, a menu called Options must be included in the interface.
This menu should contain two items: Test and Reset. On selecting the Test menu option an appropriate message should appear in the lower text field indicating whether or not the current file name is valid. After this, button presses should not be accepted until the user selects the Reset menu option to clear both text fields ready for a new file name to be entered. At other times Reset should simply clear any current filename in the top text field.
please can anyone help!
