Application of Enter Key in Powerbuilder
As we all know, the Enter key is usually suitable for confirmation, then it is necessary to use the key to enter the key in the application. 1. Enter the application in Window, such as a login window W_Login, when the user enters the username, press the Enter key, you can enter the password input. After the password is input, press the Enter key focus to move to it. Operation, according to the secondary push, then we should use the code to control: First, assume that the W_Login window is: SLE_USERNAME, SLE_PASSWORD, CB_OK and CB_CANCEL and other controls. a. Write the following code in the Modify event of SLE_USERNAME: // Script for user event ue_checkkey, // Which is mapped to pbm_keydown. if keydown (Keyenter!) THEN // Go to SLE_3 IF SLE_2.SETFOCUS () // Enter Pressed End if b. Write the following code in the Modify event in SLE_PASSWORD: // Script for User Event UE_CHECKKEY, / / WHICH IS MAPPED TO PBM_KEYDOWN. IF KeyDown (KeyEnter!) Then // Go To SLE_3 IF CB_ok.setfocus () / / ENTER PRESSED. END IF Note: The default property of the button is not advocated here. Otherwise, press the Enter key to respond to the DEFAULE attribute of the button.

When the cursor is in the last column of the current line, press the back to the key to add a number of rows, and the newly added line is used as the current line, and the first list of the current line is the current column.
