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

[mrjj]

hi
u are using
currentName=model->fileName(index);
and I sort expect it to be
currentName=model->fileName(mapped);
if u still have sort on.
//
ui->tabWidget_2->setTabText(ui->tabWİdget_2->currentIndex(),ty+"*");//this not working

ok. it looks strange. what are u trying to do ?

[takoo]

@mrjj if text change of my plainTextEdit when I want to change tab text of qtabwidget

[mrjj]

ok
and what part is not working?
Is currentindex valid?

int sel=ui->tabWİdget_2->currentIndex();
qDebug () << "sel is:" << sel;
ui->tabWidget_2->setTabText(sel,"test");

[takoo]

setTabText not working in addStar function. normally works(setTabText())

[mrjj]

@takoo
Hi
It should do the same in any slot or function.
Are you sure its called
and the index and text you use are valid?
what did
qDebug () << "sel is:" << sel;
show you?

[takoo]

sel = -1

[mrjj]

@takoo
ok. ahh.
so index is not valid.
tabWİdget_2->currentIndex() is -1 which means there is no
current/active tab.
try clicking tab before testing the text changed or change to
the first one.

How many tabs did u add to it ?

[takoo]

I am add tab with code. So It's not certain tabcount. Index only not valid in textChanged(). Otherwise valid

[takoo]

ui->tabWidget_2->setTabText(0,"tabOne"); I tried it in addStar() function but not working

[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

[mrjj]

@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

@mrjj I've identified problem. not see anything about qTabWidget in function textChanged()

[mrjj]

@takoo
Ok, im sure what u changed?

[takoo]

i sent scripts. You can see

[mrjj]

@takoo
Ohh, the function was empty??

[takoo]

@mrjj Nothing happens when I wrote related qtabwidget in that function(addStar)

[takoo]

@mrjj http://www116.zippyshare.com/v/M9f6gXaM/file.html
Try to run this project (myTabs)

[mrjj]

@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. ?

[takoo]

@mrjj hi
exactly what I need to do ?
