Scenario:
Can we have an overridden method in a dialog class. I can not use form as a dialog. I have to add a method in the dialog class. Like modified method of an EDT.
Answer:
Well it can be done. First you have to add a method dialogPostRun
public void dialogPostRun(DialogRunbase dialog)
{
;
dialog.dialogForm().formRun().controlMethodOverload(true);
dialog.dialogForm().formRun().controlMethodOverloadObject(this);
dialog.formRun().controlMethodOverload(true);
dialog.formRun().controlMethodOverloadObject(this);
super(dialog);
}
This method actually allows the dialog form to override control method at runtime. Now we need the name of the control at runtine that needs the overriden method. You can get that using
print dialogCustId.name();
pause;
where dialogCustId is the EDT. let say the name returned at runtime is Fld3_1.
Now if you have to override lookup method of the EDT you can write the method like this
void Fld3_1_lookup()
{
//override lookup method here
}
If you need to override modified method
boolean Fld3_1_modified()
{
}
.
The modified method can also be accessed by overriding
public void dialogSelectCtrl()
{
}
in the runbase class. Just call
dialog.allowUpdateOnSelectCtrl(true);
in the dialog method.
You can also create a dialog form and pass it as the parameter in the dialog method of runbase class. you can find an example in tutorial_runbase class and form.
