将在Designer中创建的QWidget添加到QToolbar

Question

I have added a new designer form class to my project that is a widget. Using designer i have added some buttons and labels etc to the widget (which i want to use as my toolbar).

The .cpp and .h files for the widget are untouched and basically just as they are when a new widget is created in qt.

i have a different form that i have added a QToolbar to and now i want to add my widegt to that tool bar

i added this code to my constructor of the form i want the toolbar on, m_horizontalToolBar was declared in the header like this std::shared_ptr<HorizontalToolbar> m_horizontalToolbar;

QToolBar *tool = new QToolBar;
tool->addWidget(m_horizontalMapToolbar.get());
this->addToolBar(tool);

this compiles and runs but nothing displays in the toolbar

I have had a look at this question

The person seems to have got it working but it doesnt really say how at all

seeing as how tool bar has an "addWidget" function i assume this is possible, any light on this would be helpful

Answer 1

您需要创建HorizontalToolbar类的实例。

m_horizontalMapToolbar = std::make_shared<HorizontalToolbar>();
