I don't do it simply because I don't know its name. The only thing I've seen yet dealing with the application class is the IMPLEMENT_APP() macro. And I tried to let a message box pop up by the time the application closes. It didn't work. void MyNewApp::OnClose( wxCloseEvent& event){ // wxMessageBox(...

SIGSEGV bei Zuweisung

Hi experts, "Vci" is a class I want to use in my program. So I coded the following: IMPLEMENT_APP( MyNewApp) bool MiniApp::OnInit(){ m_Vci1= new Vci(); frame= new CanCommFrame( NULL, -1, "CanComm", m_Vci1); SetTopWindow( frame); frame->Show( true); wxIcon icon( icoFrame); frame->SetIcon(icon); delet...

drawing example

Hi experts, i tried to draw something on a panel. The system is Windows XP with MinGW developer studio including wxWidgets 2.6.0. This is the code: void MyPanel::DrawSomeStuff(){ wxClientDC dc1( this); dc1.SetLogicalOrigin( 0, 0); //* dc1.SetAxisOrientation( true, false); //* dc1.SetUserScale( 1.0, ...

new approach: surrounding wxScrolledWindow

Hi experts, @peri_ololon: Thanks for the reply. I did not test ist myself yet, but it looks like it would be necessary to derive a class for the rightmost grid that processes its ScrollWinEvents and controls the other grids. Did I get your idea? @all: Meanwhile, I tried a different attempt: put all ...

Hi experts, many thanks to tierra. Now this example compiles and runs when linked against wxmsw26d_adv (due to wxGrid, I suppose): #include "wx/wx.h" #include "wx/grid.h" class MyApp: public wxApp{ virtual bool OnInit(); }; class MyPanel: public wxPanel{ private: wxBoxSizer* m_sz1; wxGrid* m_grdOne;...

Scrolling two windows with one scrollbar, revisited

Hi Experts, since I didn't get the real program to work, I tried to build a minimal compilable one out of the "Hello World" example. Here it is: #include "wx/wx.h" #include "wx/grid.h" class MyApp: public wxApp{ virtual bool OnInit(); }; class MyPanel: public wxPanel{ private: wxBoxSizer* m_sz1; wxG...

Hi Saurabh, I moved the MyFrame::OnGrdSumScrolled() to my wxFrame derived class. void PamaFrame::OnGrdSumScrolled( wxScrollEvent &event){ wxMessageBox( "Processing Scroll Event"); int iPixX= 0; int iPixY= 0; // m_grdData->GetScrollPixelsPerUnit( &iPixX, &iPixY); // m_grdData->SetScrollbars( iPixX, i...

Ok, then the problem is that I don't use the correct variable type? GetCellValue( 1, i).ToULong( &iDay); dtCurrentDay.SetDay( iDay); results in a wxDateTime::SetDay( unsigned long l_value) So how do I safely convert unsigned long to wxDateTime_t? can I simply SetDay((wxDateTime_t)l_value); as long a...

alternating wrong months in wxDateTime

Hi experts, there is a wxDateTime object in my code, in fact, there are many: *( m_dtCurrentSelected)= calTop->GetDate(); refers to a member variable of the main panel. When displaying some kind of schedule, this one is transferred to it: m_grdMainGrid= new ExGrid( this, -1, m_dtCurrentSelected, ); ...

Hi there,

the crashes seem to have vanished when I enshured to have one SQLFreeStmt() for every SQLAllocStmt() in the code.
