Hello!
We have a lot messages to operator from plugin and macros. Always this is a Modal Window (called via ShowDialog() function) and TopMost is true.
But I am notice that sometimes a window can be hidden when the operator changes focus to the main UCCNC window. This is not good, because the operator loses the message.
There may be special requirements for opening a modal window from a plug-in or macro. Any ideas?

The form can get behind if Windows does not know who is the parent/owner of your form.

In a macro you can try:

MyForm.ShowDialog(exec.mainform);

In a plugin you can try:

using (var DummyForm = new Form() { TopMost = true, TopLevel = true })
{
MyForm.ShowDialog(DummyForm);
}

Hmm, strange.
I have a form opened from macros via

Code: Select all

StartupForm.ShowDialog(exec.mainform);

If I try to close this form via button on the form UCCNC halted.

Code: Select all

void CancelHomeButton_Click(object sender, EventArgs e)
{
   StartupForm.Close();
}

How it's work in plugin will check Later.

Thank you!

In Plugin it's work perfect.
Thank you!

Hello Balazs!
Can you check why Frame opened from macro halt UCCNC?

Thank you!

It is likely because the macro is not on the UI thread and Showdialog tries to attach the new Form to the main form,
but the 2 forms are not in the same thread and so there is a conflict.

What you can do is you can invoke the Showdialog on the UI thread, like this:

Code: Select all

exec.mainform.Invoke(new MethodInvoker(() => UI_thr_invoke()));

#Events

void UI_thr_invoke()
{
   MyFrom.ShowDialog(exec.mainform);
}

Thank you!!!
It's work PERFECT!!
Now a big problem in the UI was solved for all of us in the plugin and macro .

Hello Balazs!
Today I had to return to the 1.2047 version and this code in macro:

Code: Select all

exec.mainform.Invoke(new MethodInvoker(() => UI_thr_invoke()));

#Events

void UI_thr_invoke()
{
   StartupForm.ShowDialog(exec.mainform);
}

causes an error and the macro does not execute.
when I return to

Code: Select all

StartupForm.ShowDialog();

All fine.

But The

Code: Select all

exec.mainform.Invoke(new MethodInvoker(() => UI_thr_invoke()));

#Events

void UI_thr_invoke()
{
   MyFrom.ShowDialog(exec.mainform);
}

works perfect in the 1.2102

Yep, .NET 2.0 does not support the lambda operator that good as .NET 4.0, so is why it does not work with the =>.
One solution is to do it like this:

Code: Select all

exec.mainform.Invoke(new MethodInvoker(UI_thr_invoke));

#Events

void UI_thr_invoke()
{
   Form MyForm = new Form();
   MyForm.ShowDialog(exec.mainform);
}

Thank you!!
