got error with DialogButton

I want to launch a customzied dialog using a DialogButton , Following the Tutorials,creating ui file, adding codes to .ymf,but unfortunatly I received a empty window.Thanks reading and sorry for my English.

link to Dialog Button sample: www.qtpyvcp.com/widgets/dialogs/index.html

ui file:


process:

It is very important to have the {{ file.dir }} directive before the UI file path in the YAML file.

So your line should look like this

This is because the YAML parser does not have any concept of file paths, so we have to prerfix any non absolute file paths with the file.dir variable which will be expanded with the directory the YAML file is located in.

I think this will solve your issue, if not let me know and I'll look deeper.

Cheers!
