| == How to execute a long running task from an action without blocking the GUI? |
| |
| The easy way if you might need to run a long task when some action is involved: |
| |
| [source,java] |
| ---- |
| |
| @ActionRegistration(asynchronous = true) |
| ... |
| public void actionPerformed(ActionEvent ev) { |
| if (isLongTaskRequired) { |
| // maybe run a ProgressHandler |
| doLongTask(); |
| } |
| EventQueue.invokeLater(new Runnable() { |
| @Override public void run() { |
| // do domething with the gui |
| } |
| }); |
| } |
| ---- |
| |
| This way you don't even need to care about threading yourself, GUI will be updated as long as the task is finished. |
