[SOLVED] QTabWidget tabName and qplaintextedit::textChanged() signal problem

[mrjj]

@takoo
sorry I am out of guesses.
if
ui->tabWidget_2->setTabText(0,"tabOne");
does not work, it have no idea then.

Did u place break point on it and made sure its called?
You are 100% sure you are adding tabs to ui->tabWidget_2 and not
ui->tabWidget_1 or something else ?

[takoo]

I am sure

@takoo
Well i'm out of guesses. sorry.
There is no reason that setTabText should not work.

please see this small sample that change tabtext when u write in edit

@takoo
hi
you create a new version of main window here

plaint::plaint(QWidget *parent):QPlainTextEdit(parent)
{
  mw=new MainWindow();<<---------------- new main wind
  connect(this,SIGNAL(textChanged()),mw,SLOT(yildiz()));
}

mw is never shown and u never see u change the tabtext in this new version you create.

in main.cpp, you already create a Mainwindow version so not sure why u create a new one. ?

@mrjj hi
exactly what I need to do ?

[mrjj]

@takoo
well It really depends what u want ?
Im not sure why you have
class plaint:public QPlainTextEdit
Instead of just using QPlainTextEdit directly ?

update:
i fixed the sample to do what u talked about first.
To change the tabtext for the tab.
