How to index Tab widget contents ?

AnneRanch

I have successfully build a common form to be used as needed.
The form has "Tab" as main widget.
Since each Tab is "indexed" , I can change desired Tab title using such index.

Each and every Tab contains QEditText widget.

How can I build a function to entry a text to the desired Tab and its QEditText?

Is there a way to "index" the QEditText widget in each Tab?

@AnneRanch
Each tab has a "page" as its widget. QWidget *QTabWidget::widget(int index) const returns the page/widget for the given tab. If you say that every one of your tabs has a QTextEdit for its widget, then:

QTextEdit *textEdit = qobject_cast<QTextEdit *>(theTabWidget->widget(tabNum));
if (textEdit != nullptr)
    qDebug() << "Success";
else
    qDebug() << "Tab number" << tabNum << "does not have a QTextEdit as its (top-level) widget";

So you can then use QTextEdit *textEdit as the text edit on tab number tabNum.

(If by chance your tab pages are actually QWidgets --- which might be how they get created in Designer --- which then contain a QTextEdit we would have to alter the code slightly, but the principle holds.)

@JonB said in How to index Tab widget contents ?:

QTextEdit *textEdit = qobject_cast<QTextEdit *>(theTabWidget->widget(tabNum));
if (textEdit != nullptr)
qDebug() << "Success";
else
qDebug() << "Tab number" << tabNum << "does not have a QTextEdit as its (top-level) widget";

Thanks, but I am little stumped.
Here is my function which basically access the tab, not the containing "page" .
QString MainWindow_C_CODE_FORM::TabTitle(QString text , int index)
{
// change tab title using index TOK
ui->tabWidget->setTabText(index,text);
// access QTextEdit ??
QTextEdit *textEdit = qobject_cast<QTextEdit *>(theTabWidget->widget(tabNum));
if (textEdit != nullptr)
qDebug() << "Success";
else
qDebug() << "Tab number" << tabNum << "does not have a QTextEdit as its (top-level) widget";

return text;

}

Can I still modify your code to work in this function?
It does not have to work in the function , I can as well write another one.

But I still do not get the access to the "page" .

I did try similar approach and it is sort-off working.
Does that makes sense ?

     MWCCF->centralWidget()->topLevelWidget()->setWindowTitle("TEST windopw TITLE");
     MWCCF->centralWidget()->topLevelWidget()->topLevelWidget()->setToolTip("TEST TAB TOOL TIP");

I have not figured out how to actually select desired Tab, so far only " top xyz..." is working.

This approach is little cryptic ,but it would bypass the need for extra sub-funtion...

I think the above "topLevel" is OK for ONE level, it doe not makes much sense for multiple level...

I like to modify / change my original post.

Is there a way to scan thru the widgets / tabs to find a tab of specific title?

I am still not sure how to find the correct widget - tab for example - pointer.
