[SOLVED] how to get tab index when only text is known?

[kalster]

I have created several tabs. when the user clicks a tab, how to get the index number of that tab when only the Text of that tab is known. I would like to store the results in a QString.

if there is no way of finding the index of a tab Text, then i guess i can store the tab Text in an array and search the array

assuming there is no duplicated tab name there, use

@
int tabIndexFound = -1;
for(int i=0; i<tab->count(); ++i) {
if(tabTextExpected == tab->tabText()) {
tabIndexFound = i;
break;
}
}
// tabIndexFound is the number you want?

yes the code will work. Gee i should have thought of that.

for anyone else reading this topic that has the same problem, note the code below...

@if(tabTextExpected == tab->tabText()) {@

should be something like...

@if(tabTextExpected == tab->tabText(i)) {@

note the "i" in the above code.

thank you joonhwan

Or just keep track of it yourself, by using a hash like this:
@
QHash<QString, int> m_tabIndices;
@

However, because it is unlikely you will have many tabs, I guess a linear search works just as well if not better. Still, in general, you should remember it does not scale very well.
