Add multiple panel objects in a sizer Topic is solved

[joepjac]

Hello,
In my Dialog I'm having problems adding a panel multiple times to a sizer. Adding has to be done by the user, for instance clicking on a button. In my example I used the OnAbout button.
I'm using it to build up kind of a list consisting of panels. The panels contain images, so I think this is only way.

It looks like the panels are not added to the BoxSizerWhereIWantToAddSomething, but to the MainBoxSizer or main dialog.
Can anyone help?

This is my code:

Code: Select all

testDialog::testDialog(wxWindow* parent,wxWindowID id)
{
    //(*Initialize(testDialog)
    Create(parent, wxID_ANY, _("wxWidgets app"), wxDefaultPosition, wxDefaultSize, wxDEFAULT_DIALOG_STYLE|wxRESIZE_BORDER, _T("wxID_ANY"));
    SetClientSize(wxSize(184,244));
    SetMinSize(wxSize(200,200));
    MainBoxSizer = new wxBoxSizer(wxVERTICAL);
    BoxSizerWithButtons = new wxBoxSizer(wxHORIZONTAL);
    Button1 = new wxButton(this, ID_BUTTON1, _("About"), wxDefaultPosition, wxDefaultSize, 0, wxDefaultValidator, _T("ID_BUTTON1"));
    BoxSizerWithButtons->Add(Button1, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 4);
    StaticLine1 = new wxStaticLine(this, ID_STATICLINE1, wxDefaultPosition, wxSize(10,-1), wxLI_HORIZONTAL, _T("ID_STATICLINE1"));

Hi,
I think you only need to add one vertical sizer to your window. Then add 1 panel to this vertical sizer containing a horizontal sizer for the buttons. Then on About simply add a new panel to the basic vertical sizer like the Test dialog in the next screenshot.
