Jface wizard dialog box on the fourth day

Content density:
Target dialog box
Content:
1. In the dialog box, each tutorial teaches how to construct a self-wizardpage class and implements
Createcontrol abstract method:
2. There are two constructor methods:
A.
Wizardpage (string pagename );
B.
Wizardpage (string pagename, String title, imagedescriptor titleimage)
3. Do not forget to call the setcontrol method after creating the control in the Wizard dialog box in the createcontrol method.
Otherwise, the control cannot be displayed,

4. When creating and assembling various Wizard Page classes, pay attention to the following issues:
The wizard must be disconnected from the wizard class, And the restore mfinish method must be implemented,
This method is called after you click "finish.
The addpage method is used to add the wizard pages to the wizard.
You must add them in order.

In addition, you can overwrite the canfinish method in the parent class to set the available status of the "finish" button.

How to implement a variety of Prompt Windows? SWT provides a class
Messagedialog
Only one OK
Messagedialog. openinformation (shell, "title", "message ");
Yes/No
Messagedialog. openconfirm (shell, "title", "message ");
Yes/No/cancel
Messagedialog dialog = new messagedialog (shell, "title", null, "message ",
Messagedialog. Question, new string [] {idialogconstants. yes_label,
Idialogconstants. no_label, idialogconstants. cancel_label}, 0 );
Dialog. open ();
You can also add more options. You only need to add more content to the array.
How can I obtain the button I clicked?
Direct int result = dialog. open ();
Or int result = dialog. getreturncode ();
The returned result value is the index of the selected button in the array.
