[Solved]creating tabs

alfah

I found a signal currentChanged for TabWidget, but i cant find out how to use it?

Any idea???

docs said

Qt Signal Documentation

@void currentChanged (int)
@
This is the default overload of this signal.

This signal is emitted whenever the current page index changes. The parameter is the new current page index position, or -1 if there isn't a new one (for example, if there are no widgets in the QTabWidget)

currentChanged will be invoked anytime you click on another tab than the current one. I don't think that is what you want or is it?

:(

yeaa u r right.

I tried using the following code, but then the same form is shown when both statics tab as well as the history tab is clicked even though i have connected two different forms
:(
@
tabWidget->widget(1)->connect(tabWidget,SIGNAL(currentChanged(int)),this,SLOT(showHistoryFrm()));
tabWidget->widget(2)->connect(tabWidget,SIGNAL(currentChanged(int)),this,SLOT(showOptionFrm()));
@

I think I don’t understand what you want exactly, maybe you could show us an image of your form ?

alfah

Rather than creating a new thread I thought its better this way,

@

tabWidget->setTabIcon(0,QIcon(":images\clock.png"));

@

The above code should set an icon in the first tab right?? But apparently its not!. I've put the image in the resource file.
???

any idea

I think you missed a ""

Try this :
@tabWidget->setTabIcon(0,QIcon(":\images\clock.png")); @

alfah

'' did not do the trick :(

Eddy

@tabWidget->setTabIcon(0,QIcon(":/images/clock.png")); @

works for me on the simulator.

the / or \ depends on your OS

alfah

ahhh, , its not workin on the simulator or the device!!

it is '/'. And i have corrected it. But still it does not work. Does image size gotta do anything with it??
ive used 16x16. its almost 900 byte

Eddy

you can test if it's available from the resource editor using a dialog in Qt Designer and set the icon from there.

alfah

Ive pulled in a tabWidget in the Designer. But i can only find iconsize property not the simple icon property with which you can set.

Eddy

no you have to use code to add it to a tab.

But you could use a QLabel just for testing if the icon is reachable through the resource editor.

alfah

it worked in the new project, both in the device as well as the simulator.
@
ui->tabWidget->setTabIcon(0,QIcon(":/images/clock.png"));
@

I think i know why it doesn work on my application.
@
tabWidget = new QTabWidget;
tabWidget->setStyleSheet("QTabWidget::tab-bar{left:0px; width:350px; }\n"
"QTabBar::tab{height:40px; width:95px; color:red; font:9pt; }\n");
tabWidget->setTabIcon(0,QIcon(":/images/clock.png"));

pCalender = new QWidget;
pHistory = new QWidget;
pStatistics= new QWidget;

connect(tabWidget,SIGNAL(currentChanged(int)),this,SLOT(onSelectTab(int)));
tabWidget->addTab(pCalender,tr("Calender"));
tabWidget->addTab(pHistory,tr("History"));
tabWidget->addTab(pStatistics,tr("Statistics"));
tabWidget->setTabIcon(0,QIcon(":/images/clock.png"));

EDIT : solved :D

bq. it worked in the new project, both in the device as well as the simulator.

so you know a good approach to solve issues yourself. Sometimes a project can grow bigger and bigger. If you make a small test project like you did you can easily narrow down to the problem. Now you know for sure that the code is right.

bq. EDIT: na i don think so, cuz widgets are placed inside the tabs not on those heading.

To be sure just comment out the lines you suspect. This one is for you ;)

alfah

ok all advises noticed and acknowledged :)

I have solved it too,

I jus needed to place the same code after the addTab function(), :) How dumb of me! How else would it put an icon if the tab not added :D :D

Eddy

Glad you solved it! You even start helping out others.

Keep up the good work!
