Angular Material – Not closing Material snackbar

The goal is to ensure you have a properly compiled QTDIR. In your case one for VS and one for gcc (if you want the two).

Depending on what you downloaded Qt Creator uses gcc but you can specify alternative QT directories under Options > Qt4 > Qt Versions. The path and version will show in the dialog box.

1. Go to the VS command line and run configure.exe & nmake with a clean source repository. Then add this QTDIR to you Qt Creator. I suggest you run make clean before.

2. Then make sure qmake and nmake can be run from the Qt command-line without errors. You should have a Qt Command line icon installed if you used Qt installer. If not, make sure you have QTDIR environment variable set, with %QTDIR%/bin in the path.

3. Do step 1 again, but this time do not use VS but make sure gcc is in the path. Run configure.exe etc again but in a separate directory specially for gcc. Add this version to your Qt Creator.

4. When compiling your project, run qmake first. You can change Qt versions, but do not forget to run qmake.

Hope this helps.

In your component SnackBarComponentExample try:

saveButtonClick = () =>{
  let config = new MatSnackBarConfig();
  config.duration = 5000;
  config.panelClass = ['red-snackbar']
  this.snackBar.open("This is a message!", "ACTION", config);
}

Where 'red-snackbar' is a class in your apps main styles.css file. Strangely I was unable to get the config.panelClass to work when I was referencing my components associated css file, but once I put the class into the main styles.css file my styles were applied correctly to the snackBar.
