Hi, Guys!
I created a thread class based QThread, and defined some signals to
update UI through main thread.
the UI used a stackedWidget,someone page named 'progressPage' have a
progressBar and a Label, the next page named 'resultsPage' shows
results(some Labels).
When the window showed progressPage, my code that updates progressBar
was well, but the updating resultsPage's labels signals seems ignored
by main thread.(I guess, because I added some prints in the slot, it
wasn't printed)
the code like this:
1. class worker(QtCore.QThread):
2. sig_jump_finish_page = QtCore.pyqtSignal()
3. sig_set_label_text = QtCore.pyqtSignal(str, str)
4. sig_set_progress_value = QtCore.pyqtSignal(int)
5.
6. for dirpath, dirnames, filenames in os.walk(self.root):
7. for filename in filenames:
8. self.sig_set_label_text.emit('current', self.current()) # work well
9. # so something
10.
11. #self.dialog.set_found(str(self.found())) # work well
12. #self.dialog.set_all(str(self.total())) # work well
13. self.sig_set_label_text.emit('found', str(self.found())) # :(
14. self.sig_set_label_text.emit('all', str(self.total())) # :(
15.
16. self.sig_jump_finish_page.emit()
So I have to update UI directly in the thread(comments Line 11-12
shows), it looks work well.
I found the difference between line 8 and line 13-14 is line 8
manipulates current page -progressPage, line 13-14 manipulates next
page -resultsPage.
Is some wrongs in there?
Have a look at my comments:
class worker(QtCore.QThread):
sig_jump_finish_page = QtCore.pyqtSignal()
sig_set_label_text = QtCore.pyqtSignal(str, str)
sig_set_progress_value = QtCore.pyqtSignal(int)
for dirpath, dirnames, filenames in os.walk(self.root): # What is 'self'
here ?
for filename in filenames:
self.sig_set_label_text.emit('current', self.current()) # where is
'current' ?
# so something
#self.dialog.set_found(str(self.found())) # What is self, and dialog,
and found ?
#self.dialog.set_all(str(self.total())) # ...
self.sig_set_label_text.emit('found', str(self.found())) # again ?
self.sig_set_label_text.emit('all', str(self.total())) # etc
self.sig_jump_finish_page.emit()
