add items to treewidget

[Shien]

Hi,

I have tree widget with 2 columns. But I don't know how to insert there data.

With spin box I want to choose row and then choosing from combo box value insert it into selected row. What would be easiest way to do this? Because I tried all day and nothing good happened.

[high_flyer]

What exactly is your problem?
Inserting items to the tree?
Combining the the spinbox and combo and tree?
And then in detail - what part?
If you want help, then please post enough information about the problem you have, what you have tried, the errors you get ect.
No one has time to try and guess what you have done, and what not.

Because I tried all day and nothing good happened.

This has no meaningful information to someone who wants to help you.

ApplyDwellersTypeButton slot shoud use values from dwNumberSpinbox as key where to put dwTypeCombo value.

This is the hardest way, I don't know how to do this.
Can anyone help me?

[high_flyer]

I don't know how to do this.

Do what?
Connect a signal to slot?
Again, please explain what the problem is that you have!

[Shien]

When I choose values from dwNumberSpinbox and dwTypeCombo and cliking apply. It should put dwTypeCombo's value to row(dwNumberSpinbox.value) in tree widget's second column.

thats the idea.

[high_flyer]

Ok, so now we know what you want it to do.
And what is the problem you have?
Note: problem != "should do".

[Shien]

First I thought that I would be able to simple to insert it into treeW with insertTopLevelItem function. In order of int index I tried to use dwNumberSpinbox->value() maybe it was good choise I don't know . because I don't how create treewidgetItem which has value of dwTypeCombo

[high_flyer]

because I don't how create treewidgetItem which has value of dwTypeCombo

Let me see if I understand:
you want to create a QTreeWidgetItem() that holds the value of the current selected item in the combobox?
Is that it?

[Shien]

something like that. while choosing swNumberSpinbox value and dwTypeCombo value to fully fill treewidget. Is it possible?

[high_flyer]

I am sorry, I just can't seem to understand you, and you seem unwilling to say what the problem is - which is strange if you want help.
Maybe someone else understands what your problems is, I don't.

Can't you say something along the lines of:
"I have done XXXX, in order to achive YYYY and I have problems figuring ZZZZZ out." ?!
Or anything that will explain the PROBLEM you have?

Is it possible?

"Everything" is possible.

[aamer4yu]

May be QTreeWidget::insertTopLevelItem will help you

[norobro]

Or QTreeWidget::topLevelItem and QTreeWidgetItem::setText

[Shien]

Can't you say something along the lines of:
"I have done XXXX, in order to achive YYYY and I have problems figuring ZZZZZ out." ?!
Or anything that will explain the PROBLEM you have?

I am making simple game editor. It's my studies project. Wich creates games objects. Now am trying to make planets editing part

So I managed to add elements to treewidget, but only on the first column. Can anyone tell me how to put it into second one?
Or make it as a child?

I tried to create child, but I don't know how him to put into treewidget any ideas?
Another problem is with is when I am putting dwTypeItem because now item is simple putted down on dwNumberSpinbox->value() index. But when I am filling lets say 3 items. then first one is added in corect place. but others in wrong order beacause I ussing insertTopLevelItem. after I put first element order of others becomes wrong. And I don't know how to correct it. I tired with if construction but nothing good happened.

[norobro]

Can anyone tell me how to put it into second one?

Did you investigate QTreeWidget::topLevelItem and QTreeWidgetItem::setText ?

Looks to me like this should work:

void CreatePlanet::applyDwellersTypeButtonClicked()
{
    int row = dwNumberSpinbox->value()-1;
    QString text = dwTypeCombo->currentText();
    treeW->topLevelItem(row)->setText(1,text);
 
}

void CreatePlanet::applyDwellersTypeButtonClicked()
{
    int row = dwNumberSpinbox->value()-1;
    QString text = dwTypeCombo->currentText();
    treeW->topLevelItem(row)->setText(1,text);

}

[Shien]

Thanks it worked.

[Shien]

again problem with treewidget. last time I wanted to add value form combo box. Now I need to add spinbox value. this is best what i came up with

QTreeWidgetItem *item = new QTreeWidgetItem(satelliteSizeSpinbox->value());
    treeW2->insertTopLevelItem(starSatelliteNumberSpinbox->value(),item);

QTreeWidgetItem *item = new QTreeWidgetItem(satelliteSizeSpinbox->value());
    treeW2->insertTopLevelItem(starSatelliteNumberSpinbox->value(),item);

To copy to clipboard, switch view to plain text mode 

and again I want to put it on second column
