Trouble getting SFML working with my Win32 window.

[Jallen]

Ok, I am making an editor for my game using SFML to display the GUI and Irrlicht to display the viewport. My problem is that the SFML part isn't working at all, it should be in that little light patch on the right (it's light because thats the window colour, sfml is literally not displaying at all, not even a blank colour)


This is my WinMain

Code: [Select]

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
HWND hWnd = InitialiseWin32Window(hInstance);
Viewport* viewport = new Viewport(hWnd, hInstance);
ControlPanel* controlpanel = new ControlPanel(hWnd, hInstance);

MSG msg;
while(true)
{
if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
if(msg.message == WM_QUIT)
break;
}
viewport->Run();
controlpanel->Run();
Sleep(0);
}
delete controlpanel;
delete viewport;
return 0;
}

Control Panel header

Code: [Select]

#ifndef ControlPanel_h
#define ControlPanel_h

#include <windows.h>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>

class ControlPanel
{
public:
ControlPanel(HWND hWnd, HINSTANCE hInstance);
~ControlPanel();

void Run();

protected:
HWND SfmlControlPanel;
sf::RenderWindow* renderpanel;
};

#endif

And Control Panel source file

Code: [Select]

#include "ControlPanel.h"

ControlPanel::ControlPanel(HWND hWnd, HINSTANCE hInstance)
{
SfmlControlPanel = CreateWindowW(L"STATIC", NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS,
864, 0, 160, 600, hWnd, NULL, hInstance, NULL);
renderpanel = new sf::RenderWindow(hWnd);
}

ControlPanel::~ControlPanel()
{
delete renderpanel;
}

void ControlPanel::Run()
{
renderpanel->Clear(sf::Color(255,0,0));
renderpanel->Display();
}

I really have no idea why it's not working, as you can see I am trying to display that entire rectangle as red and nothing is displaying at all.
As you can see irrlicht is working correctly, so it shouldn't be a problem with my main window.

Thanks

Do you use the OpenGL backend of Irrlicht? Can you show your Viewport class?

[Jallen]

I used the DX9 renderer in Irrlicht, it works very similar to SFML with win32 integration.

Here are my viewport files.

Header

Code: [Select]

#ifndef Viewport_h
#define Viewport_h

#include <windows.h>
#include <irrlicht.h>

class Viewport
{
public:
Viewport(HWND hWnd, HINSTANCE hInstance);
~Viewport();

void Run();

protected:
HWND irrlichtViewport;
irr::IrrlichtDevice* device;
irr::video::IVideoDriver* driver;
irr::scene::ISceneManager* smgr;
};

#endif

Source File

Code: [Select]

#include "Viewport.h"

Viewport::Viewport(HWND hWnd, HINSTANCE hInstance)
{
irrlichtViewport = CreateWindowW(L"STATIC", NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS,
0, 0, 864, 600, hWnd, NULL, hInstance, NULL);

irr::SIrrlichtCreationParameters params;
params.DriverType = irr::video::EDT_DIRECT3D9;
params.WindowId = reinterpret_cast<void*>(irrlichtViewport);

device = irr::createDeviceEx(params);

driver = device->getVideoDriver();
smgr = device->getSceneManager();

smgr->addCameraSceneNode(0, irr::core::vector3df(5,5,5),irr::core::vector3df(0,0,0));
irr::scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(smgr->getMesh("../Media/floortile.obj"));
node->setMaterialFlag(irr::video::EMF_LIGHTING, false);

}

Viewport::~Viewport()
{
device->closeDevice();
device->drop();
}

void Viewport::Run()
{
device->getTimer()->tick();
driver->beginScene(true, true, irr::video::SColor(255, 50, 50, 50));
smgr->drawAll();
driver->endScene();
}

Does the SFML view work if you remove your Irrlicht viewport?

[Jallen]

Strangely it draws from 0, 0 to 864, 600...

That is most confusing considering the definition of CreateWindowW is as so...

Code: [Select]

CreateWindowW(lpClassName, lpWindowName, dwStyle, x, y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)
Which should mean that based on this...

Code: [Select]

SfmlControlPanel = CreateWindowW(L"STATIC", NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS,
864, 0, 160, 600, hWnd, NULL, hInstance, NULL);
that the following should be true in my function call:

Code: [Select]

lpClassName = "STATIC"
lpWindowName = NULL
dwStyle = WS_CHILD | WS_VISIBLE | QS_CLIPSIBLINGS
x = 864
y = 0
nWidth = 160
nHeight = 600
hWndParent = hWnd
hMenu = NULL
hInstance = hInstance
lpParam = NULL
Surely then the sfml render panel should range from 864, 0 to 864+160, 0+600 in my window?...


Ok this is getting REALLY wierd.

Code: [Select]

SfmlControlPanel = CreateWindowW(L"STATIC", NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS,
100, 0, 160, 600, hWnd, NULL, hInstance, NULL);
That does this:

It's like it's occupying the inverse of the areas specified, VERY peculiar.
Possible sfml bug bug?

[Jallen]

OK, SFML BUG IDENTIFIED
You appear to be using the width and height where you should be using x and y and using x and y where you should be using width and height.

Ok no bug afterall

[Laurent]

Hum... I have a simpler conclusion: you use the wrong HWND

Code: [Select]

renderpanel = new sf::RenderWindow(SfmlControlPanel); // <--- you initially used hWnd

[Jallen]

Oh man I feel so stupid, how could I have missed that D:

Thanks so much, and sorry about labelling it a bug based on my sillyness

[Nexus]

Oh, suddenly the font size of "SFML BUG IDENTIFIED" shrunk drastically.

(Sorry for OT)

[Jallen]

Hmm, is it possible for my SFML view on my win32 window to get events via this interface?

Code: [Select]

const sf::Input& input = renderpanel->GetInput();

Absolutely, it should work fine. SFML subclasses the window in order to catch all its events, so that it behaves like SFML-made windows.
