I capture left button double click in TabMouseMsg() to close currenct view as samples do on RBUTTONDOWN to create a popup menu on MDITab but it doesnt work! I use XTP 8.70 I check the code and find LBUTTONDBCLK is the same position as RBUTTONDOWN, but why can't i catch LBUTTONDBCLK as sample does in MainFrm.cpp |

ON_MESSAGE(WM_XTP_PRETRANSLATEMOUSEMSG, OnTabbarMouseMsg) LRESULT CMainFrame::OnTabbarMouseMsg(WPARAM wParam,LPARAM lParam) if (wParam == WM_LBUTTONDBCLK) { ... return TRUE; return FALSE } ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

I had done that before I asked here! Actually, I wrote as LRESULT CMainFrame::OnTabbarMouseMsg(WPARAM wParam,LPARAM lParam) if (wParam == WM_LBUTTONDBCLK) { return TRUE; Even in your mditab sample, i just add a branch do deal WM_LBUTTONDBCLK, it doesn't work too! I try another message WM_LBUTTONDOWN, it can be captured in ON_MESSAGE(WM_XTP_PRETRANSLATEMOUSEMSG, OnTabbarMouseMsg) Why this happens? |

ok, you catch me, I didn't test it. :) You need to patch source code to make it work. Find AfxRegisterWndClass(0, LoadCursor(0, IDC_ARROW) in XTPTabClientWnd.cpp and replace it to AfxRegisterWndClass(CS_DBLCLKS, LoadCursor(0, IDC_ARROW)

Sorry Oleg, I tried as you told! But nothing changed!  And I checked MSDN, AfxRegisterWndClass(0, LoadCursor(0, IDC_ARROW) if the first input parameter is NULL, that means the style is CS_DBLCLKS! Is this the solution for my question after testing? |

Yes, I tested it. Be sure you rebuild dll and _use it_ (may be you need to copy it in debug folder) ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

oleg! I failed! I did what you said! I replaced 0->CS_DBCLKS in XTPClientWnd.cpp's Addworkspace(); But i must emphasized I used XTP8.7! We used different version or you patch more than the only file! |

Hmm. I think you have EnableGroups option enabled do you have VERIFY(m_MTIClientWnd.Attach(this)); or VERIFY(m_MTIClientWnd.Attach(this, TRUE)); ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Thanks oleg! I solve it! Now, I disable Groups Option on MTIClientWnd like this, as you said! m_MTIClientWnd.Attach(this)// I had used m_MTIClientWnd.Attach(this, TRUE), so can't capture &nbs p; &nbs p; &nbs p; &nbs p; // the double clicks on MDITab Now It works! And why this happens? Why groups enable, The WM_LBUTTONDBCLK is missed! |

If groups enabled, MDIClient has no CS_DBLCLICK style. to fix it for groups add: SetClassLong(m_MTIClientWnd.GetSafeHwnd(), GCL_STYLE, GetClassLong(m_MTIClientWnd.GetSafeHwnd(), GCL_STYLE) | CS_DBLCLKS); ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |
