Question

In Qt Designer I’m creating multiple labels (for instance):

my_label1
my_label2
my_label3
...
my_label n

Then if I want to hide them I do this:

ui->my_label1->hide();
ui->my_label2->hide();
ui->my_label3->hide();
...
ui->my_labeln->hide();

However I would like to define the labels like

my_label[n]

So then I would be able to do this:

for(i=0;i<n;i++)
    {
    ui->my_label[n]->hide();
    }

I read that I can define the widget like:

QLabel* my_label[5];

but is there any way to do the same from Qt Designer?

Thanks in advance!

Finally I decided to do direct assignment:

QLabel* my_label_array[5];
my_label_array[0] = ui->my_label1;
my_label_array[1] = ui->my_label2;
my_label_array[2] = ui->my_label3;
my_label_array[3] = ui->my_label4;
my_label_array[4] = ui->my_label5;

Then I can do for instance:

for(idx=0;idx<6;idx++) my_label_array[idx]->show();
for(idx=0;idx<6;idx++) my_label_array[idx]->hide();
for(idx=0;idx<6;idx++) my_label_array[idx]->setEnabled(1);
for(idx=0;idx<6;idx++) my_label_array[idx]->setDisabled(1);
etc...

Then I was able to perform iterations. I believe is not the cleanest way to do it but given my basic knowledge of Qt is ok for me.
