savefiledialog

问题 I need to customize default Qt save file dialog: add some options in it. For example, adding some checkboxes with my own values in it between file type and save/close buttons. Have Qt any ways to do it? 回答1: You can customize the Qt file dialog as long as you're okay with using the "non-native" Qt file dialog that comes with Qt; the other option Qt provides is to use the OS's native file dialog, but if you do that there is no way (that I'm aware of) to customize the dialog.

问题 I am trying to save a file using GetSaveFileName and want to have a couple extra popups at the bottom of my save file dialog to allow the user to specify further options.

问题 My program is supposed to create a text file, but it is adding invisible unrecognized char(s) to the beginning of the text file. I can only see the invisible unrecognized char(s) when scanned. I was able to get the char(s) to go away by opening with word pad instead of notepad, typing a char, and backspacing then saving. That fixed the file, but I need to correct the code causing it. Am I messing up the file type and its adding a random char? Here is code for dialog and file name/type: Try
