If the file name is too long, how to make the file selection drop-down box of the QT editor display the file name completely?

Sometimes the name is longer for file categorization. There is no need to limit the width of the file name drop-down box. I recommend that the editor be improved here.Rare does not mean no, tooltip shows file names that are not intuitive，at least the file name drop box should be able to set the growth can be dragged adjustable
