Turbo Badger implementation

I’ve had this for over a month now, and progress has been slow. I don’t foresee any modifications that I need to do to the port itself, so I feel confident enough in releasing this. However this implementation makes several assumptions that will not be true for everyone, so some modification may be required to fit your specific needs.

This is primarily based off the existing Urho3D UI implementation, so there will be a lot of similarities.

It still uses Urho3D resources to load files, so turbobadger file paths are the same as loading any files through Urho3D. I did hard-code the skin and override skin paths in TBUI.cpp, so you may need to change these if you use different paths.

To setup the subsystem:

// Setup Turbo Badger UI
UI::TBUI::RegisterSystem(_context);
_context->RegisterSubsystem(new UI::TBUI(_context));
_context->GetSubsystem<UI::TBUI>()->Init();

Adding an editor control that expands the entire window is easy:

_editorUI = ui->LoadWidget<tb::TBWidget>("UI/ui_resources/editor_tab_content.tb.txt");
ui->SetRoot(_editorUI);

Great share!

Excellent, thanks blue

Initialize subsystem (assuming similar namespace setup):

  // Setup Turbo Badger UI
  context_->RegisterSubsystem(new App::UI::TBUI(context_));
  context_->GetSubsystem<App::UI::TBUI>()->Init();

A little example to working with events, including input.

Working with Carnalis’ example, your class needs to inherit from TBWidgetListener and set itself as a global event handler. This example is for clicking a button called “fileMenu”, and showing a popup window with the File menu options:

bool Editor::OnWidgetInvokeEvent(tb::TBWidget *widget, const tb::TBWidgetEvent &ev)
{
	if (ev.target->GetID() == tb::TBID("fileMenu"))
	{
		if (ev.type == tb::EVENT_TYPE_CLICK)
		{
			static tb::TBGenericStringItemSource source;
			if (!source.GetNumItems())
			{
				source.AddItem(new tb::TBGenericStringItem("New", tb::TBID("default font")));
				source.AddItem(new tb::TBGenericStringItem("Open File", tb::TBID("large font")));
				source.AddItem(new tb::TBGenericStringItem("-"));
				source.AddItem(new tb::TBGenericStringItem("Save", tb::TBID("large font")));
				source.AddItem(new tb::TBGenericStringItem("Save All", tb::TBID("large font")));
				source.AddItem(new tb::TBGenericStringItem("-"));
				source.AddItem(new tb::TBGenericStringItem("Exit", tb::TBID("align left")));
			}

			if (tb::TBMenuWindow *menu = new tb::TBMenuWindow(widget, tb::TBID("popup_menu")))
			{
				menu->Show(&source, tb::TBPopupAlignment());
			}
		}
	}
}

Very slick UI
Candidate for Urho3D? I really like the way TurboBadger does things, it seems rather complete, internationalized…

A TurboBadger Console (Urho3D::Object, TBWidget) inspired by Urho3D::Console.

Still a couple rough edges…
Being a TBWidget, it’s easily styled and modified. I did not implement SetNumLines() (calc the line height) but it shouldn’t be hard.

Besides Urho3D’s Console, the TurboBadger Demo application was helpful in developing this, and can offer a lot of insight.

After instantiating TBUI and creating a root widget…

Console* console(new ::Console(context_, tbRoot));
console->LoadResourceFile("UI/resources/console.txt"); // required widgets
console->Initialize();
// Change custom styles for LOG_* constants (output widget in console.txt has 'styling 1')..
console->styleMap_[LOG_ERROR] = Pair<String, String>("<color #ff0000>", "</color>");
console->Toggle(); // It's invisible by default

console->SetID(TBIDC("console"));
// Can be later retrieved by ID:
// Console* console(static_cast<Console*>(tbRoot->GetWidgetByID(TBIDC("console"))));

I’m looking at your code and Atomic’s code for the first time, and it looks like you copied and pasted Atomics code. From rendering process to key inputs, they’re identical.

Well, I guess it’s ok if you gave him credit for his work.

Wow, I’m surprize to see Atomic’s UIInput.cpp file is almost as long as my entire integration.

Input stuff I got from Atomic. Rendering stuff was based on Urho3D’s existing UI class. The reason our code base looks similar is because we both used UI as our base. However Atomic uses a functionally different batching process which I skipped altogether. I actually finished the rendering part before I took a look at Atomic, but I got stuck on “proper” input support and filesystem stuff.

I see. It would’ve been nice to see a reference.

I am glad that some of the Atomic code was useful.

I don’t really mind for snippets, though when sharing in the “Code Exchange” section for others to use, probably a good idea to leave copyright and license notifications in place

Granted, it’s less “leaving them in place” and more “adding them to the post”. The Atomic MIT license is in the correct place for the next release, whenever that will be.

There’s no need from here to remove code from posts, I was just mentioning that when sharing code for others to use, good to cite sources and licenses of where pulling code from… even with the permissive MIT, in any event cheers

I think the implementation that was posted still exists and I’ll look to posting that when it’s available.

Here is my own working edition of the implementation. Changes include a license header (let me know if it needs further changes), some private to protected members, various updates for Urho3D, formatting. no real API changes that I recall…

Thanks a lot.

[quote=“carnalis”]I think the implementation that was posted still exists and I’ll look to posting that when it’s available.

Here is my own working edition of the implementation. Changes include a license header (let me know if it needs further changes), some private to protected members, various updates for Urho3D, formatting. no real API changes that I recall…

tb_Urho3D.h

tb_Urho3D.cpp

Is this really complete? Because i can not get it working.

Edit:
For the next poor soul that bumps into same thing here is working example:

TurboBadgerUI::RegisterSystem(context_); tbui.Init("TBUI/language/lng_en.tb.txt"); tbui.LoadSkin("TBUI/default_skin/skin.tb.txt"); tbui.AddFontInfo("TBUI/vera.ttf", "Vera"); tbui.SetDefaultFont("Vera", 14); tbui.SetRoot(new tb::TBWidget()); auto window = tbui.LoadWidget<tb::TBWindow>("TBUI/ui_resources/test_layout01.tb.txt"); tbui.GetRoot()->AddChild(window); tbui.ResizeWidgetToFitContent(window);

For some reason default fotns (.tb.txt) did not work however ttf fonts work fine. Also trick was to call tbui.ResizeWidgetToFitContent(window); because for some reason widget size initially seems to be 0;0.

Really nice class by the way. I love it how its two files handling all the integration. Thanks.

To configure tb/tb_config.h for Linux, I enable #define TB_FONT_RENDERER_TBBF, enable TB_FONT_RENDERER_FREETYPE, undefine TB_FILE_POSIX (we’re using TBUrho3DFile), and it was similar for MSWindows.

And yes, to solve a problem we all had: ResizeWidgetToFitContent() was written to size widgets which are not within a top-level widget like TBWindow (TB docs did not make this clear at the time).

Here is my TB-Urho3D setup code *edit: added more context

If it is help to someone, here is the tb_Urho3D originally posted by Thebluefish. Note that it does not include my updates; I only added the license header.

Hi,
Turbo Badger looks great and I want to use it as the UI for my application. So, a few minutes ago
I git clone Turbo Badger from Github and followed the instruction to clone GLFW as a submodule. All went well including its compilation, but unfortunately TurboBadgerDemo appear as an image cornered to the lower left side of the window.

BTW, I’m on OS X El Capitan.

Don.

Hey guys it seems that GetSubsystem()->SetTouchEmulation(true) is blocking the mouse events from Turbo Badger. Is there anyway around this?

I have not seen that yet… If this is just with TB’s own demo, maybe there is some issue there? github.com/fruxo/turbobadger/issues

Urho (rokups) recently added some events that allow us to hook the raw events and consume them. I have not yet worked this into the tb_Urho3D implementation, so if anyone has a good way to suggest, that’s welcome.

E_INPUTBEGIN : input handling starts.
E_INPUTEND : input handling ends.
E_SDLRAWINPUT
    URHO3D_PARAM(P_SDL_EVENT, SdlEvent);           // SDL_Event*
    URHO3D_PARAM(P_CONSUMED, Consumed);            // bool

github.com/urho3d/Urho3D/blob/a … nts.h#L224

In touch emulation mode mouse events are intentionally not sent, so that you can see the effect of only touch events and not get them mixed. Touch events should be hooked to TB too to make it work correctly with touch.

I think this is great and a really good implementation however i would rather see a version that is more urho compatible.Instead of implementing it as an external subsystem why not wrap it like the other libraries ? So the default Urho3D::UI should use TurboBadger ? Im not familiar with TurboBadger but i think it would be even possible to add some CMake configuration to build Urho3d with the default UI or with TurboBadger.
So this way :
1 will work out of box (at some point)
2 the Urho3D Editor would work with TurboBadger widgets without any major code modifications
3 Without code modifications it is automatically exposed to Scripts too.

I don’t think you can reasonably expect to code to the same API if you switch the underlying UI library, except by simplifying a lot, and that wouldn’t benefit the good parts of either UI library.

This has been discussed before and I do think the ideal would be for the UI library to be wrapped so that you use e.g. Urho events and Urho resources instead of the UI library’s native ones. However in practice it’s a very difficult ideal, since either you have a lot of wrapping/adaptation work to do, or lose features. Compare to Bullet: Urho’s physics components don’t expose Bullet nearly completely so for a physics power user using Bullet directly could actually make more sense.

Yes , these are the modifications i mention , but yes this would require a lot lot work ,when probably after TurboBadger integration the default UI would be obsolete anyway.So maybe it would be better just switching to TurboBadger as the UI (by using the existing UI unterface and expanding it).Maybe it worth a new branch for testing this.

Well i would rather lose features than using api’s directly.Thats the main reason i like Urho3d.It’s clear and easily understandable interface.Once you learned the coding workflow you don’t need extra tutorials to get into other features.By using apis directly you always have to learn the new library first…Which isn’t really attractive for new users

here’s a screen shot of my modified gui skin.I added some shadows , highlights to buttons and switched to monochrome style.I think it is more pleasant for the eyes than the deafult blue style.
