delete/add layout, or modify existing layout?

[jpn]

I'd suggest using QStackedWidget (or QStackedLayout). It'll save you from flickering problems.

thanks jpn. From Assistant: "QStackedLayout class provids a stack of widgets where only one widget is visible at a time." Is there a Class in which I could put a stack of Layouts? ...so that only one layout is visible at a time?

Any Ideas here? I have my layouts, but I still don't know how to delete (or hide) them from the rootLayout.

//creates 5 QHBoxLayouts
for(int a=0; a<5; a++)
{
  createLayouts(a);
}
 
 
rootLayout->addLayout(layout[0]);  //only adds the first layout
 
   //  function() will hide/remove "layout[0]" and show/add layout[1]
connect(mainButton1, SIGNAL(clicked()), this, SLOT(function()));

//creates 5 QHBoxLayouts
for(int a=0; a<5; a++)
{
  createLayouts(a);
}


rootLayout->addLayout(layout[0]);  //only adds the first layout

   //  function() will hide/remove "layout[0]" and show/add layout[1]
connect(mainButton1, SIGNAL(clicked()), this, SLOT(function()));

To copy to clipboard, switch view to plain text mode 

but I don't see a way to hide or remove the first layout[0]

Install each layout on a plain QWidget and add them to a QStackedWidget.

Sorry for such a short answer, I was in hurry. Anyway, as mentioned, I'd suggest installing each layout on a plain QWidget and then adding them to a QStackedWidget. Furthermore, you may construct a QButtonGroup out of the main buttons for switching pages more or less like this:

QStackedWidget* stack = new QStackedWidget(this);
...
QWidget* page1 = new QWidget(stack);
page1->setLayout(layout[0]);
stack->addWidget(page1);
...
QWidget* page2 = new QWidget(stack);
page1->setLayout(layout[1]);
stack->addWidget(page2);
...
QButtonGroup* group = new QButtonGroup(this);
group->addButton(btn1, 0); // "page1" at index 0
group->addButton(btn2, 1); // "page2" at index 1
...
connect(group, SIGNAL(buttonClicked(int)), stack, SLOT(setCurrentIndex(int)));

QStackedWidget* stack = new QStackedWidget(this);
...
QWidget* page1 = new QWidget(stack);
page1->setLayout(layout[0]);
stack->addWidget(page1);
...
QWidget* page2 = new QWidget(stack);
page1->setLayout(layout[1]);
stack->addWidget(page2);
...
QButtonGroup* group = new QButtonGroup(this);
group->addButton(btn1, 0); // "page1" at index 0
group->addButton(btn2, 1); // "page2" at index 1
...
connect(group, SIGNAL(buttonClicked(int)), stack, SLOT(setCurrentIndex(int)));

gotcha (i think): create 5 layouts with their respective widgets (buttons & labels). Also create 5 QWidgets; do:

myQWidget_0->addLayout(myLayout_0);

myQWidget_0->addLayout(myLayout_0);

To copy to clipboard, switch view to plain text mode 

for myQWidgets 0-4, then use QStackWidget to manage.

...working on it.

just saw your second response: excellent, thanks for the advice/direction.
