Last modified date is not reflecting instantly
I have implemented simple tree view in which i want to show file_name and its last modified date (2 columns). tree view has also add and remove button to add or remove files from tree view. now the problem is that when i add any file and if i will modify that file externally (like from text editor something like that) then it is not instantly showing me last modified date in tree view.
I have to close my application and then again after reopening it, it showing me my changes
I have used QDateTime lastModified() function for that?
What changes should i implement so that it will change instantly?
why not try
connect its signal to your model's slot.
