DockWidget with Direct3D Widget and expanding problem

[anda_skoa]

Did you call setWidget() on the dock widget?

Cheers,

So i just created a QVBoxLayout based on the code snippet above, but still got the same results.

EditorSceneWindow file

void EditorSceneWindow::Create(WeakPtr<Engine> engine) {
	engine_ = engine;
 
	QVBoxLayout* layout = new QVBoxLayout(this);
 
	d3dRendererWidget_ = new D3DRenderWidget(this, engine_);
	layout->addWidget(d3dRendererWidget_);
 
	this->setLayout(layout);
}

void EditorSceneWindow::Create(WeakPtr<Engine> engine) {
	engine_ = engine;

	QVBoxLayout* layout = new QVBoxLayout(this);

	d3dRendererWidget_ = new D3DRenderWidget(this, engine_);
	layout->addWidget(d3dRendererWidget_);

	this->setLayout(layout);
}

D3DRenderWidget file

D3DRenderWidget::D3DRenderWidget(QWidget* parent, Engine* engine) :
	QWidget(parent) {
 
	setAttribute(Qt::WA_PaintOnScreen, true);
	setAttribute(Qt::WA_NativeWindow, true);
 
	QSizePolicy sizePolicy = this->sizePolicy();
	setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::MinimumExpanding);
}

D3DRenderWidget::D3DRenderWidget(QWidget* parent, Engine* engine) :
	QWidget(parent) {

	setAttribute(Qt::WA_PaintOnScreen, true);
	setAttribute(Qt::WA_NativeWindow, true);

	QSizePolicy sizePolicy = this->sizePolicy();
	setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::MinimumExpanding);
}

Did you try calling QDockWidget::setWidget() as anda_skoa suggested?

Does your render widget have an inherent size? Or do you have to set it somewhere? Presumably if you are going to use it to render something with Direct3D, you need to give it a size somewhere. What happens if you call resize( 300, 300 ) (for example) in the render widget constructor?
