Hi,
I'm trying to load a config file to my Java Service in the Viewpoint Specification Project. I hope to put a button in the Property View and once I click on it, a File Selector Dialog comes out so I can choose from where I will load the config file. But I didn't find something like a File Selector, does Sirius support such a widget?
Thanks very much for your help.

Hello,

Indeed, I do not think that we have a widget that prompts the File Browser. You will have to create a classic button, and in the model action of this button, call a java service that will open the File Browser. In this java service, you will need to have the following action to prompt the System file browser:
FileDialog fileDialog = new FileDialog(shell, SWT.OPEN);
fileDialog.setText("title");
String filePath = fileDialog.open();

Best regards,
Steve

Hi Steve,
I tried java swt in my project to invoke a FileDialog. However, there is an Error saying Invalid thread access. I searched for the internet and found that this is caused by java swt's display thread not created. I also found some examples telling me how to create FileDialog, but all the examples says that I have to change the Button's Listener method, which I have no idea how to configure them in Sirius. Would you please help me about how to use swt FileDialog in detail? Just an example is fine.
Thank you very much.
