 |
|
Greetings.
I have this sub,
| Code: | final void NewReportForm()
{
Form f;
with(f = new Form)
{
text = "Choose What Report To Create";
startPosition = dfl.form.FormStartPosition.CENTER_PARENT;
with(new Button)
{
text = "Combined";
location = Point(2, 2);
parent = f;
click ~= &CombinedReportClick;
}
with(new Button)
{
text = "TimeUsage";
location = Point(2, 42);
parent = f;
click ~= &TimeUsageReportClick;
}
show();
}
}
|
and it works fine, but I want to close that window after one of the button has been clicked. I tried a few things, but it is not working. I know it's something simple, but what it is? I know it is f.close(), but where do I put it so that it happens after the click?
thanks. |

Just close the form in the button's click event... (CombinedReportClick or TimeUsageReportClick)
Perhaps you are confused because you no longer have a reference to the form (from what I gather from your snippet). You can either save a reference to it, or pull it from the sender's parent:
| Code: | void CombinedReportClick(Control sender, EventArgs ea)
{
(cast(Form)sender.parent).close(); // Close through parent. parent must be the Form.
} |
As a side note, I always thought it'd be cool if D let you specify the context of a delegate literal, instead of always inferring it from the scope. It could let you 'attach' a delegate to your Form inline without actually having to define a member function for it in the class definition. It could simplify a lot of these cases where the delegate is needed beyond the lifetime of the stack frame. If you don't know what I mean you can just ignore this. |

I tried this,
| Code: | private void TimeUsageReportClick(Object sender, EventArgs ea)
{
msgBox("TimeUsageReport.");
(cast(Form)sender.parent).close(); // Close through parent. parent must be the Form.
}
|
But it is not working. How do I call it from the parent? I am getting,
| Code: | 20:11:06.61>build -I..;c:\dmd\import -version=gui -version=Phobos OpenJobs.d
OpenJobs.d(4040): Error: no property 'parent' for type 'object.Object'
Error: cannot cast int to dfl.form.Form |
Also, I know what you are talking about. I may not understand it as deep as you, but I know what you are saying...  |

| Code: |
void TimeUsageReportClick(Object sender, EventArgs ea)
// error
|
| Code: |
void CombinedReportClick(Control sender, EventArgs ea)
// right

private void initializeMyForm() {
}
}
int main()
{
int result = 0;
try
{
new XForm();
}
catch(Object o)
{
msgBox(o.toString(), "Fatal Error", MsgBoxButtons.OK, MsgBoxIcon.ERROR);
result = 1;
}
return result;
}

thank you for your help. After seeing your example, I rewrote my program to follow your declarations and I now got it to work...
Thanks.
