Sometimes Scene Builder in JavaFX doesn't open
Even though this question has been asked some time ago, I want to contribute my solution to this problem because it differs from the other solutions and in addition is very simple.
This particular problem happened to me just a few mins ago and all I took to solve was maximizing the actual Scenebuilder window!
- Open the Windows Taskmanager
- Switch to the applications tab
- Right click the SceneBuilder (named: yourFileName.fxml)
- Select 'Maximize'
Description above works for Windows OS, on other OS the corresponding application managing program should do the same.
That worked for me just perfect. No copying and/or overwriting needed.
Its not the perfect answer but it works well. Try doing the following
1.Open scene builder directly from your local drive.
2.Click on File-> Open Recent -> Clear Menu
Then try to open up your fxml. Works fine for me.
