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

SGaist

Hi,

What is text_Changed ? If it's a slot, how is it connected ?

takoo

connect(ui->plainTextEdit,SIGNAL(textChanged()),this,SLOT(addStar()));

mrjj

hi
connect(ui->plainTextEdit,SIGNAL(textChanged()),this,SLOT(addStar()));
This connects to addStar() and not
text_Changed() ?
also , to make sure connect works, you can
QDebug() << " Text Change Signal:" << connect(ui->plainTextEdit,SIGNAL(textChanged()),this,SLOT(addStar()));
and see it returns true.

takoo

result true . Only does not print qstring (currentName) in addStart() function

mrjj

@takoo said:

qDebug()<<currentName;

well try with
qDebug()<<"hello";

where is currentName defined? where do u set the value?

takoo

i have tried and result="hello" .

void MainWindow::on_treeView_doubleClicked(const QModelIndex &index)

{

if(index.isValid())
{
Q

ModelIndex mapped=filter->mapToSource(index);
i=index;

currentName=model->fileName(index);
sampleString=currentName;

}
}
void MainWindow::text_Changed()
{
qDebug()<<sampleString; // currentName writes
ui->tabWidget_2->setTabText(ui->tabWİdget_2->currentIndex(),ty+"*");//this not working

}

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
