Running a window
During development, you can test a window without running the
whole application.
You can preview a window from the Window painter using the Preview
button on the PainterBar or run the window by clicking the Preview
button on the PowerBar. The PowerTip text for this button is Run/Preview
Object. For information about previewing using the PainterBar button,
see Previewing a window.
When you run the window using the PowerBar button, you must save
the window first. You can also trigger events and open other windows
because the window is functional.
To run a window:
-
Click the Preview button in the PowerBar (not the
PainterBar). -
In the Run/Preview dialog box, select Windows as the Objects
of Type. -
Select the target that includes the window you want to
run. -
Select the library that includes the window.
-
Select the window you want to run and click OK.
You must save your work before running a window. If you have
not saved your work, PowerBuilder prompts you to do so.PowerBuilder runs the window.
You can trigger events, open other windows, connect to a database,
and so on when running a window. The window is fully functional. It has
access to global variables that you have defined for the application and
to built-in global variables, such as SQLCA. The SystemError event is
not triggered if there is an error, because SystemError is an
Application object event.
To return to the Window painter:
-
Do one of the following:
-
If the Window has a control menu, select Close from the
control menu or click the Close button in the upper right corner
of the window. -
If the window is not visible, click PowerBuilder on the
task bar and then click the Terminate button.
