dialog

问题 I'm building a WPF app and trying to conform to MVVM best practices. I'm using the MVVM Foundation framework and noticed the Messenger class, which I've read should be used for handling dialogs in WPF. This sounds great, but I'm totally not understanding how to use a Messenger for this purpose. Literally, all I want to do is open a modal About dialog --I don't need to pass any messages back and forth. Was the intent of the Messenger class to be used for cases where dialogs require a message

问题 Opening a gtk FileChooserDialog is painfully slow for nfs directories containing many files. strace shows a lot of time calling "stat". About 5 calls for each of the files in the directory. How can we switch off the calls to 'stat' and just show a list of filenames without the modification time? We're using operating Redhat enterprise 4, x86_64, Linux 2.6.9-42.0.8.ELsmp and FileChooser is coming from: /usr/lib64/libgtk-x11-2.0.so.0.400.13 . A test program opens a FileChooserDialog and takes

问题 I have a button that when clicked, a dialog box opens up with various controls on it such as radio buttons and text boxes. If OK then the values in that dialog box is passed back to the button and the rest of the code is processed with those values. If Cancel then do nothing. How can I do this? I was thinking of making another form with those controls and have that button call the new form but I want the rest of the controls to stop until the form is completed like a dialog box. 回答1: 1.)

问题 Whenever I launch the Visual Studio 2015 Publish Web Dialogue (or Visual Studio 2013, both have the same issue) for a specific project, it takes ~20-30 seconds for it to open. Just as well, when I switch between publish profiles it takes the same amount of time when I switch to a specific one . When I switch to Profile A in the list (from Profile B) it takes the same amount of time as it does when it launches the dialogue itself. When I switch from Profile A to the Profile B it doesn't take

问题 I am new to Android and this is my first question here so please go easy on me. Is it possible to check some condition inside onCreate() of an Activity and display an AlertDialog? I am creating an AlertDialog anonymously in Oncreate() and calling show on that instance but the AlertDialog is never displayed. 回答1: Showing an alert dialog in onCreate causes android.view.WindowLeaked exception, because the activity isn't yet created. The solution I found is to put the code that shows the dialog
