How to launch a table with columns' names set as checkboxes' labels
-
Ok about launching the mainwindow after the wizard winds up i did this:
@
int ConclusionPage::nextId() const
{
connect(this, SIGNAL(buttonClicked(QWizard::FinishButton)), window, SLOT(LaunchWidget()));
return -1;
}
@
to my conclusion page that contains the finish button, window is an object pointer to the class MainWindow. LaunchWidget() is a slot that enables the central widget which was previously set to launch a text edit for experimental purposes to see if it would work. LaunchWidget() is defined in the MainWindow and is called right after the constructor.But when i compile it returns this error:
@
C:\mystuff\maprojo\SkoolCalc\SkoolCalcWizard.cpp:312: error: no matching function for call to 'ConclusionPage::connect(const ConclusionPage* const, const char [38], MainWindow* const&, const char [16]) const'
@is there anything wrong with my implementation apart from the error??

Your wizard should not know anything about your MainWindow, that creates a useless tight coupling. You should rather connect the finished signal from your wizard to the LaunchWidget slot in your MainWindow
-
By knowing about the mainwindow object do you mean not declaring it in the wizard header and imlplementation files?? Because AFAIK i have done what you've just written above apart from the wizard not knowing about the window which will need some more elaboration??

What is most common is this:
@
WizardLoadMapFile LoadMapWizard(this);LoadMapWizard.setFileName(FileName_str); if (LoadMapWizard.exec() == QDialog::Accepted) { this->m_NewFileName = LoadMapWizard.m_MapFileName; emit signal(m_NewFileName); // Just an example }@
Where the WizardLoadMapFile is the QWizard inherited class that contains member variables holding the needed information that the mainWindow needs to construct the table (or something else) -
What about just launching the mainwindow with a textedit central widget just after the wizard button finish is clicked in the conclusion page. My mainwindow is set to launch a textedit for now for experimental purposes which is currently disabled, but i want to launch it once the conclusion page winds up??

To me, it is no so clear anymore what your actual problem is at the moment. SGaist gave you some valuable suggestions already. What did you do with those?
However, I doubt a stringlist is the best data structure for this purpose. What would be in the strings exactly? I guess you don't have an endless variety of columns you can display and populate. One the one hand it is inefficient to use strings to contain static names for columns, and on the other is is not a good idea to use translatable strings for application logic. So, if your set of possible columns is indeed limited, I'd simply make an enum for them and use a QFlags (or as QVector<ColumnEnum> if ordering is important) to communicate the columns to display.

That's sorted out. My problem now is launching the table in the mainwindow's central widget(it's currently set to disabled) immediately the finish button is clicked in the conclusion page of the wizard. The code above shows my attempt, but it apparently doesn't work!!
-
It doesn't and it's not the best design either.
Did you try the suggestion of Jeroentj@home ?

The technique is still valid. Once the wizard is ended do the stuff you want with your central widget even if you don't use the information from your wizard.

Connect your wizard to your MainWindow inside your MainWindow, not your wizard.
