There is a small bug in this program. The tray icon does not disappear ! immediately when the program terminates. Instead, it remains in the system ! tray until you point the mouse cursor at it, when it disappears. This is a bug ! in Win32::GUI - when you close your program, you should explicitly remove any ! system tray icons you still have displayed. Referring to the example above, ! you should place this line after the Win32::GUI::Dialog() call: $main->NI->Delete(-id => 1); - Hopefully, this will be fixed in a later version. - =back --- 151,159 ---- =item * !

B<Note:> There is a related option, C<< -ok => 1 >>, which has a similar ! effect as C<-default>. However, the two seem to conflict in their effects.

What's happening here is that we requested a C<W2_Terminate> action, and since we didn't provide an event for this, Win32::GUI proceeds with the default behaviour for the close button, which is to destroy ! the window. The result is that you can't show $W2 anymore, because ! it does not exists anymore as a valid window (although it still exists ! as a Perl object). To let our window survive the close action, we need ! to provide a customary C<Terminate> event: sub W2_Terminate { --- 141,152 ---- If you choose to close the second window with the Close (little X) ! button on the upper right corner, you'll notice that all the windows ! disappear. What's happening here is that we requested a C<W2_Terminate> action, and since we didn't provide an event for this, Win32::GUI proceeds with the default behaviour for the close button, which is to destroy ! the window, and exit the windows message loop.

[ This section is out of date. Win32::GUI has native support ! for modal windows. See the DoModal() method in the main documention.] Here is another very common functionality you may want to implement: --- 159,163 ---- that we can show it again using the button in C<$W1>. ! =head2 "modal" windows Here is another very common functionality you may want to implement: *************** *** 173,198 **** program unless you have disposed of it. ! Win32::GUI does not have direct support for modal windows, but you can ! simulate the behaviour with this trick: ! sub W1_Activate { ! if($W2->IsVisible) { ! $W2->SetForegroundWindow(); ! return 0; ! } ! return 1; } ! The meaning should be obvious enough: if the popup window is shown, ! trying to activate the main window automatically reports you to the ! popup window; otherwise, the main window becomes the active one as ! normal. Of course, if you have more than one popup window, you should ! add code for everyone of them: ! sub W1_Activate { ! if($W2->IsVisible) { $W2->SetForegroundWindow(); return 0; } ! if($W3->IsVisible) { $W3->SetForegroundWindow(); return 0; } ! # ... and so on ! return 1; } --- 167,234 ---- program unless you have disposed of it. ! So, the behaviour of a modal window is to diable interaction with the ! window used to launch it (know as its parent window). To achieve this ! we first have to tell the window who its parent is. We do this when we ! create W2, using the C<-parent> option: ! $W2 = new Win32::GUI::Window( ! ... ! -parent => $W1, ! ); ! ! Now, when we want to display the W2 we use the C<DoModal()> method: this ! disables W2's parent window (W1), and starts a new message loop to ! process events for W2. When we are done with W2, we return C<-1> from an ! event handler, which causes C<DoModal()> to return, but in this case does ! not cause any of the windows to be destroyed. Here's the full code: ! ! use Win32::GUI; ! ! my $W1 = Win32::GUI::Window->new( ! -name => "W1", ! -title => "First Window", ! -pos => [ 100, 100 ], ! -size => [ 300, 200 ], ! ); ! ! $W1->AddButton( ! -name => "Button1", ! -text => "Open popup window", ! -pos => [ 10, 10 ], ! ); ! ! my $W2 = Win32::GUI::Window->new( ! -name => "W2", ! -title => "Second Window", ! -pos => [ 150, 150 ], ! -size => [ 300, 200 ], ! -parent => $W1, ! ); ! ! $W2->AddButton( ! -name => "Button2", ! -text => "Close this window", ! -pos => [ 10, 10 ], ! ); ! ! $W1->Show(); ! Win32::GUI::Dialog(); ! exit(0); ! ! sub W1_Terminate { ! return -1; } ! sub Button1_Click { ! $W2->DoModal(); ! return 0; ! } ! sub W2_Terminate { ! return -1; ! } ! ! sub Button2_Click { ! return -1; } |
