[SOLVED] Rendering something ABOVE the console?

[Amerio.Stephane]

Hi, I'm trying to have a sprite render over the console. The doc says Widget::setOrder() can be used, with a value from -127 for the profiler and 127 for the console.

I tried 127, but the console is still above. I tried 255, but nope, still it displays below the console. Is it possible to force something above the console?

Rationale: we are displaying binary data encoded into the image, which is video recorded, and then later decoded. But sometimes we need to open the console and this will corrupt the encoded data, of course.

Hello,

For widgets 127 is the maximum order value. Set this value for the widget and also use the flags ALIGN_OVERLAP and ALIGN_FIXED when adding to the window. Here is a small example:

int AppSystemLogic::init()
{
	ImagePtr img = Image::create();
	img->create2D(256, 256, Image::FORMAT_RGBA8);
	for (int i = 0; i < 256; i++)
	{
		for (int j = 0; j < 256; j++)
			img->set2D(i, j, Image::Pixel(0, 255, 0, 255));
	}

	WidgetSpritePtr overlap_sprite = WidgetSprite::create();
	overlap_sprite->setImage(img);
	overlap_sprite->setOrder(127);

	EngineWindowPtr main_window = WindowManager::getMainWindow();
	main_window->addChild(overlap_sprite, Gui::ALIGN_OVERLAP | Gui::ALIGN_FIXED);

	return 1;
}

Hum nope, doesn't work for me :(

Same code, same location. Maybe there is something else that could interfere?

Are you using 2.16.1 SDK?

Yes, 2.16.1

Is the console used only in one window or in several?

[karpych11]

Each window contains a WidgetVBox which is responsible for the widgets in the client area. The idea was to add the sprite after adding the console and not let it reorder. For a test you can try adding this widget last among all the widgets in the window. For example:

int AppSystemLogic::update()
{
	EngineWindowPtr main_window = WindowManager::getMainWindow();
	int num = main_window->getNumChildren();
	if (num != 0 && main_window->getChild(num - 1) != overlap_sprite)
	{
		overlap_sprite->setParent(nullptr);
		overlap_sprite->setOrder(127);
		main_window->addChild(overlap_sprite, Gui::ALIGN_OVERLAP);
		overlap_sprite->setFlags(Gui::ALIGN_OVERLAP | Gui::ALIGN_FIXED);
	}

	return 1;
}

It works with this code! Thanks!
