Thanks Alan, at this point I decided I needed to buy the book in order to keep up with you. Following along from Chiapas, Mexico.

Interesting note, following along on macOS, at ~10:30, working on adding "Quit" to the file menu. If you call your action "Quit" or "Exit" it will not show up in the menu. If you call it _Quit or Q_u_i_t it will show up, but you cannot add an action called literally Quit. Also of note, self.close DOES work when you call it something else. This is on macOS 10.15.5 for reference.

Hi, I run the code in the description and I have one question. The 'search' works to the opened txt file, but why does the 'search' doesn't work when I searched something to the sentence I've just typed in the textedit?

[@gordonwilson1740]

For those using PyQt6 (I couldn't load PyQt5), there are a couple minor changes to make this work. Line 64 at about 22:58 needs to be modified... line 64 --> self.addDockWidget(qtc.Qt.DockWidgetArea.RightDockWidgetArea, search_dock) The term "DockWidgetArea" has been added. Also, earlier moving the cursor to the start of the opened text file can either be commented out or modified as follows... line 88(?) --> self.textedit.moveCursor(qtg.QTextCursor.MoveOperation.Start) The term "MoveOperation" has been added. I'm using a Mac so maybe your experience will be different. I also found that "sys.exit(app.exec_())" on the last line did not work at all for me. Maybe Qt are going to claim the reserved word "exec" was for them. ; )

Another one... line 25 --> self.case_checkbox.checkState() == qtc.Qt.CheckState.Checked Added the term "CheckState"... == qtc.Qt.Checked ---> == qtc.Qt.CheckState.Checked

[@gordonwilson1740]

Yet another... line 96 --> qtg.QTextDocument.FindFlag.FindCaseSensitively Adds the term "FindFlag" before "FindCaseSensitively"

Thanks. When I copied the code (that I triple-checked for accuracy, I just get: class MainWindow(qtw, QMainWindow): NameError: name 'QMainWindow' is not defined I thought who knows? Maybe if I do from PyQt5 import QMainWindow maybe that would fix it. Do you or does anybody know why I might be getting that error?

[@alandmoorecodes3585]

It should be qtw.QMainWindow.

[@johntobin9404]

@@alandmoorecodes3585 Alrighty. Thanks, Alan. Will try that.

Why don't you pass *args and *kwargs for a Qmain window?
