Hi
i m creating one dialog using designer...dialog conatins one treeWidget.
I m making this this dialog as public...
Ui::Dialog dlg;
In the construtor i m calling setupUi(this); its working....
but i want to use this treeWidget in other class...i m using obj of this class...
obj->dlg.treeWidget in other class...but its not working...where m i missing...
Well, how exactly are you using it? Is it in other thread?
Is the dialog created( setupUi and all ) when you use it?
Could you post some relevant code?
some code for this ...
//first file
#include "ui_Dialog.h"
Header file
public:
Ui::Dialog dlg;
cpp file
Constructor part of FIRST class
{
dlg.setupUi(this);
dlg.treeWidget->setColumnCount(2);
}
///Second class
header class
private:
FIRST *first;
//cpp file
void SECOND::func()
{
QTreeWidgetItem *pItem = NULL;
pItem = new QTreeWidgetItem(first->dlg.treeWidget);
pItem->setText(0,"root");
}
///But is not connecting to the FIRST class...not display text "root" in treeWidget ...why
The problem is that you did not instantiate FIRST in the SECOND class.
You have to create FIRST to be able to use it like that. Something like:
first = new FIRST();
i already instantialted like this in my class
first = new FIRST();
still it is not working....
In the constructor of FIRST:
it is setupUi( this ) not dlg.setupUi( this ).
If you get any errors after replacing that, please post them
What does "not working" exactly mean in this case? Does it compile?Quote:
