Refer to the example code in the Examples3_Java database for details. When the user clicks the same column again, the rows are sorted in descending order. By clicking a column, the user sorts the rows in ascending order using that column's entry as the basis for sorting. The frmKeyStrokes example also provides sample code for sorting rows. The getSelectedRowCursor() method returns an agiRowCursor object, which points to the selected row. Similarly, get the pressed modifier(s) by calling getModifiers(), and get the String that describes the modifier(s) by calling getKeyModifersText().īefore displaying the names of the key and modifiers, check that the Alt key is not pressed by calling isAltDown().Ĭall setText() from fldKey and fldModifier to display the names of the key and modifiers in the respective text fields.Ĭheck if the pressed key is the Delete key. ![]() Get the String that describes the key code by calling getKeyText() and providing the key code as its parameter. Get the integer key code associated with the pressed key by calling getKe圜ode(). If it's the delete key, delete the current row As long as it is not Alt, show the key and modifier text in the text boxes String sModifier = keyEvent.getKeyModifiersText (keyEvent.getModifiers()) String sKey = keyEvent.getKeyText(iKe圜ode) Get the key that was hit and the modifier, if any ![]() Private void handle_vwEmployeeList_keyPressed(KeyEvent keyEvent) This code lets the Alt modifier continue to normal processing and it handles the Delete key differently-in addition to displaying the name of the Delete key, it deletes the selected row on the form. It then displays the pressed key and modifier (if the user presses one) in the form's Modifier and Key text fields by using the setText() method. It uses getKeyModifiersText to get the text representing the modifier (such as Shift or Ctrl) that the user hits. The textarea should then insert a new line. the enter key test then emulate an enter key by creating an event object. The idea I suggested is to trap keystrokes in the text area, If the enter key is pressed, do the submit method. Just as a screen may contain many application. the form, AND cause the F6 key to do what the enter key used to do inside. The code uses getKeycode() to get the integer representing the key that the user hits. When you type at the keyboard, it is understood that your keystrokes are directed at the current window. The following code runs only if the view ( vwEmployeeList) is the current focus, so make sure you click it first. It also shows how you can define a new behavior for processing the keystroke or let the keystroke continue to its normal processing. The example shows how to intercept the processing of a keystroke by getting its key code.
