How to setBottomWidget insteads of setCentralWidget? and color? (solved)

[houmingc]

Is there other container that i can use other than QVBoxLayout.
what does showEvent and hideEvent do exactly in ticker.cpp?

can give more guidance for this problem?

To work with QMainWindow's central widget you have to create a container widget and work on it. I already wrote that setting a layout on a QMainWindow will fail since it already has one.

@
QWidget *containerWidget = new QWidget;
QVBoxLayout *layout = new QVBoxLayout(containerWidget);
layout->addStretch(1);
layout->addWidget(pTicker);
setCentralWidget(containerWidget);

--How to remove former layout---

under ui->setupUi(this);
I inserted: delete layout();

before adding your code. No progress.

Again: stop trying to put your own layout in QMainWindow, it's not meant for that.

deleted mainwindow source file.
Insert above code into main instead.
compiler complain setCentralWidget was not declared in this scope.

Sure it's not, it's meant to be used in a QMainWindow subclass constructor
