Using the QT Development Text editor (a): Introduction to Functions

have been very envious of others can develop text editor, later learned QT, see the example inside, their own transformation, unexpectedly also can get a out, although said is not very strong, right when is one of their own learning results. Okay, I'll just cut the crap and go straight to the chase. This text editor mainly implements the following functions:

(1) text editing (including Undo, Redo, save, open file, export to PDF, Save as, etc.).

(2) tab-style document.

(3) The line number is displayed.

(4) The edits are converted to uppercase or lowercase.

(5) Font change.

(6) Editor settings.

(7) Go to the specified line.

MFC is far away, with QT,MFC is bullshit, for the original to give up MFC feel fortunate.
