I am trying to open a sprite in UI.

// in init function

g_SampleUI.SetCallback( OnGUIEvent ); int iY = 5;
g_SampleUI.AddButton( IDC_BUTTN, L"Button", 400, iY, 70, 22 );

int nSprite = g_DialogResourceManager.AddTexture(L"Masa.jpg");
CDXUTElement element;
SetRect(&r, 0, 0, 200, 200);
element.SetTexture(nSprite, &r);

IDC_BUTTN is working well but i can't see the sprinte in the window.Where am i doing wrong ? Do you have any idea about it ?

debug step by step, and you'll notive that if the alpha of the element's texture color is 0, the sprite is not rendered.


element.TextureColor.Current.a = 1.0f
element.TextureColor.Current.r = 1.0f

should help.

Oh, I didn't fully understand what you wrote.

It won't work because the sprite starts on the beginning of the Render method of the CDXUTDialog, and ends at the end of the same method.

So when you call CDXUTDialog::DrawSprite from anywhere but inside the Render method of the dialog, it's not inside the ID3DXSprite::Begin / ID3DXSprite::end pair, and it won't draw (turning DirectX runtime to Debug would show a waring / error in the Visual output)

If you want to add a sprite, one solution that I would recommend is to create a new control. You can take the CDXUTStatic class as an example. Duplicate it, change its name, get rid of all the stuff you don't need, and add the AddSprite(), GetSprite(), etc. method to the CDXUTDialog.

And then, in the CDXUTSprite::Render() method, you will be able to draw a sprite with "m_pDialog->DrawSprite(...);"
