Sample framework on a panel

Sample framework on a panel

• j_m_d

  Hi,

  Has anyone managed to get the latest version of the Sample Framework (Feb 2006 and Dec 2005) to work with full mouse and keyboard events. (I have added my code at the bottom of this post)

  I have been trying now for 2 weeks with no luck. I can see the mouse messages on the form and by adding hooks to the mouse on InitialiseGraphics() I can also capture the mouse message in the directx application but I am not sure how I can pass this onto the framework to process so that when I press the left mouse button and move the mouse the model will move on screen. This works perfectly if I use CreateWindow but not if I use SetWindow.

  I am using Simple Animation from the SDK browser and have removed the CreateWindow(..) and replaced it with:

  sampleFramework.SetWindow(frm, frm, frm, true);

  where frm is the form control (eventually it will be a panel) where I want the directx rendered to.

  What I have done so far is created a new project that shows a form called Form1.
  I next referenced the simple animation project from the SDK and changed the outout type to class output in the project preferences.

  I next renamed main() to InitialiseGraphics() in the Simple Animation sample so that there is only one Main() which resides in Form1.cs

  On the constructor to Simple Animation I pass in the form reference, create a new Framework and pass the form reference to InitialiseGraphics() above.

  InitialiseGraphics will now call SetWindow() using the frm reference passed in. I have also added some hooks to MouseDown and MouseMove but am not sure if these will be useful for passing messages to the sample framework.

  I remove the last line:
  sampleFramework.MainLoop()
  and instead I call RunLoop() from form1 main (see below):

  Thank you in advanced for your help / advice etc (esp if you think I am coding this incorrectly - I am from an embedded c background not an object oriented background).

  ================= CODE BELOW ===============

  Form1 main() function looks like this:

  static void Main()
  {
  Application.EnableVisualStyles();
  Guardian_GUI.GuardianGui frmGui = new GuardianGui();
  dxViewer.dxViewer viewer = new dxViewer.dxViewer(frmGui);
  viewer.RunLoop(frmGui);
  frmGui.Close();
  return;
  }
  
  
  
  Simple Animation (was main) InitialiseGraphics() looks like this:
  
  

  public dxViewer(System.Windows.Forms.Form frm)
  {
  // Store framework
  this.sampleFramework = new Framework();

  // Create dialogs
  hud = new Dialog(sampleFramework);

  // Initialise Everything
  InitialiseGraphics(frm);
  }

  public int InitialiseGraphics(System.Windows.Forms.Form frm)

  {

  // Set the callback functions. These functions allow the sample framework to notify

  // the application about device changes, user input, and windows messages. The

  // callbacks are optional so you need only set callbacks for events you're interested

  // in. However, if you don't handle the device reset/lost callbacks then the sample

  // framework won't be able to reset your device since the application must first

  // release all device resources before resetting. Likewise, if you don't handle the

  // device created/destroyed callbacks then the sample framework won't be able to

  // recreate your device resources.

  sampleFramework.Disposing += new EventHandler(this.OnDestroyDevice);
  sampleFramework.DeviceLost += new EventHandler(this.OnLostDevice);
  sampleFramework.DeviceCreated += new DeviceEventHandler(this.OnCreateDevice);
  sampleFramework.DeviceReset += new DeviceEventHandler(this.OnResetDevice);
  sampleFramework.SetWndProcCallback(new WndProcCallback(this.OnMsgProc));
  sampleFramework.SetCallbackInterface(this);

  try
  {
  // Show the cursor and clip it when in full screen
  sampleFramework.SetCursorSettings(true, true);

  // Initialize
  this.InitializeApplication();

  // Initialize the sample framework and create the desired window and Direct3D
  // device for the application. Calling each of these functions is optional, but they
  // allow you to set several options which control the behavior of the sampleFramework.

  sampleFramework.Initialize(true, true, true); // Parse the command line, handle the default hotkeys, and show msgboxes

  //sampleFramework.CreateWindow("dxViewer");
  //sampleFramework.SetWinformWindow(frm, frm, frm);

  sampleFramework.SetWindow(frm, frm, frm, true);

  // Hook the keyboard event
  sampleFramework.Window.KeyDown += new System.Windows.Forms.KeyEventHandler(this.OnKeyEvent);

  //sampleFramework.Window.MouseMove += new System.Windows.Forms.MouseEventHandler(this.OnMouseMove);

  //sampleFramework.Window.MouseDown += new System.Windows.Forms.MouseEventHandler(this.OnMouseDown);

  sampleFramework.CreateDevice(0, true, frm.Width-100, frm.Height-100, this);

  // Pass control to the sample framework for handling the message pump and
  // dispatching render calls. The sample framework will call your FrameMove
  // and FrameRender callback when there is idle time between handling window messages.

  //sampleFramework.MainLoop();
  }
  #if(DEBUG)
  catch (Exception e)
  {

  // In debug mode show this error (maybe - depending on settings)
  sampleFramework.DisplayErrorMessage(e);
  #else
  catch
  {
  // In release mode fail silently
  #endif

  // Ignore any exceptions here, they would have been handled by other areas

  return (sampleFramework.ExitCode == 0) 1 : sampleFramework.ExitCode; // Return an error code here
  }

  // Perform any application-level cleanup here. Direct3D device resources are released within the
  // appropriate callback functions and therefore don't require any cleanup code here.

  return sampleFramework.ExitCode;
  }//END FUNCTION

  private void OnMouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
  {
  // Mouse Down captured here but I dont know how to pass this message onto the framework for processing
  }

  private void OnMouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
  {
  // Mouse Move captured here but I dont know how to pass this message onto the framework for processing
  }

  Thanks Glenn... I actually came across this site a few days ago but I dismised it because I thought it doesn't do what I needed

  Even though I now got the framework to run in a panel it doesn't work as expected
  (I'm rendering a teapot and I can see through it and similar stuff).
  So I gave up and I'm starting from scratch :)

  Have a look at the following sample, it uses the sample framework inside a windows panel, it might be what you are looking for.

  I did a little experimenting myself and came up with this:
  
  I created a DirectXPanel class which creates the framework
  and instead of the original EmptyProject example calls
  SetWindow and passes itself as the parameter:

  sampleFramework.SetWindow(this, this, this, true);

  in the Framework code I changed every reference to System.Windows.Forms.Form to
  System.Windows.Forms.Panel and then had to fix some code
  (mostly commented out Form.Close, Form.State, ... statements)
  
  But this doesn't work :(
  
  The device gets created, the frame gets rendered but when the Device.Present method is called it throws an exception:

  at Microsoft.DirectX.Direct3D.Device.Present(tagRECT* pSource, tagRECT* pDest, HWND__* hOverride)
  at Microsoft.DirectX.Direct3D.Device.Present()
  at Microsoft.Samples.DirectX.UtilityToolkit.Framework.Render3DEnvironment() in D:\temp\EmptyProject_2005\Common\wdxmut.cs:line 2563

  with the exception code E_FAIL

  What does E_FAIL mean

  All answers will be greately appreciated (I should mention I'm in a bit of a hurry :) ),
