Creating a keypress signal from application button

maxmotor

That was it, thank you :)

Okay to get back to the subject (Which I slowly turned away from introducing other challenges :) ).

I have made a slot in MyTableView:

@void MyTableView::key_down(){
QTableView::moveCursor(QAbstractItemView::MoveDown, Qt::NoModifier);
}@

This is then used in my setup.cpp file:

@void Setup::createActions() {

QObject::connect(ui.buttonTwo, SIGNAL(clicked()), this, SLOT(myTableViewInstance->key_down()));

}@

This has no effect on my QTableWidget though. But I guess it's me and my coding which is faulty again. Can you see from my code snippets what I'm doing wrong?

@ connect(ui.buttonTwo, SIGNAL(clicked()), myTableViewInstance, SLOT(key_down()));
@

maxmotor

I get this error: 'QObject' is an inaccessible base of 'MyTableView'

vsorokin

Please show MyTableView constructor implementation

maxmotor

It is empty :/

@MyTableView::MyTableView(QWidget* parent) : QTableView(parent){

}@

vsorokin

oh... I haven't more ideas :)

Try change
@#include "qtableview.h"@
to

@#include <QTableView>@

if nothing changes, just put all your sources to file hosting and get me link :)

maxmotor

I have sent you a link :)

vsorokin

Oh... many points:

In your sources
@class MyTableView: private QTableView {@

although, in example above you wrote:
@class MyTableView: public QTableView {@

You don't needed MyTableView, you already have QTabletWidget on form
You don't needed inheritance in this case.
In setup.cpp
I rewrite some things:
It's for local slot, because MyTableView not needed anymore
@connect(ui.buttonTwo, SIGNAL(clicked()), this, SLOT(down()));@

in slot, as example, you can add any checks and other logic to their:
@void Setup::down() {
Parent_ui::ui.tableWidget->selectRow(Parent_ui::ui.tableWidget->currentRow() + 1);
}@

same for up slot:
@void Setup::up() {
Parent_ui::ui.tableWidget->selectRow(Parent_ui::ui.tableWidget->currentRow() -1);

}@

Vass you are very kind!

I will have a look at this the first thing in the morning.

Especially you and ludde have been a big help so far dealing with my lack of Qt/C++ skills.

Thank you guys!

I just wanted to tell you that my code is now working as intended! - Thanks to you!

I'm very impressed of the willingness to help out on this forum. And the fast response was superb.

I'm almost positive that we will talk again! ;)

Thank you so much for your time!

Glad to hear! :)
However, I highly recommend you learning C++ - it just save your time in future
