c++ - Append missing extension to result of QFileDialog -


By using

QFileDialog , I prompt the user for a file name and add an extension I am missing.

One suggestion was to add an extension manually after the fact that the problem with this approach is that the user can not be warned that they are overwriting the file (for example, test.txt exists, the user enters test and is not indicated that they are actually overwriting test.txt )

I have read all the documents on QFileDialog and I E has not been successful. I tried setDefaultSuffix , but the result of fileDialog.getSaveFileName () was not expanded. Can someone provide an example of how to do it successfully?

Unfortunately, it seems that when you are using the "native" file dialog, this functionality Not available . However, it works as if you expect that you use the QT file dialog.

Here's how you can use the QT file dialog: 

  QFileDialog saveDialog; SaveDialog.setAcceptMode (QFileDialog :: AcceptSave); SaveDialog.setDefaultSuffix ("txt"); SaveDialog.exec (); QString file = saveDialog.selectedFiles (). first ();   
 As an alternative, you can apply your own overwrite verification:  
  QString file; Do {file = QFileDialog :: getSaveFileName (); If (! File.endsWith (".txt")) {file.append (".txt"); If (QFile :: exist (file)) {if (QMessageBox :: Yes! = QMessageBox :: question (NULL, QString (), "Confirmation Overwrite?", QMessageBox :: Yes | QMessageBox :: No) {file. clear(); }}}} Whereas (file.isEmpty ());

How can I add a seperate action listener to all 14 of my buttons at once that can determine player turn?(java) -

I have a big code, for a game I'm calling Tommy's Kumamak. I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
