Need layout help

[Udo Baumgart]

Hi,

i try....

What i want is the following:

MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm
LLLLLLBmmmmmmmmmmmmmmmmmmmmmmmmmm

MMMMMM = Menubar
TTTTTT = Toolbar
LLLLLL = Left userinterface area
B      = Button
mmmmmm = Main document area

LLLLLL should become vertically scrollable if the window size is to
small to display all interface elements.

I tried to use a wxScrolledWindow for LLLLL which contains a couple of
sliders (for now as dummy content).

But as soon as the scrollbars appear, the virtual size of the area inside
the scrolledwindow grows and grows and grows... Altough there is no change
inside the elements...
For more details see my first post to this thread which includes a sample
"myframe" which is commented and should be usable to see the effect. Just
compile and link the following sources, try to resize the window to a
small size and look what happens... Looks VERY strange to me and i am not
able to find a solution....

Here is the complete sourcecode (out of Code::Blocks). I am using Windows  
XP
with wx2.8.0 monolithic unicode build.

----------app.cpp-----------------
#include "app.h"
#include "main.h"

IMPLEMENT_APP(MyApp);

bool MyApp::OnInit()
{
	MyFrame* frame = new MyFrame(0L, _("wxWidgets Application Template"));
	frame->Show();
	return true;
}


--------- app.h -------------------
#ifndef APP_H
#define APP_H

#include <wx/wxprec.h>

#ifdef __BORLANDC__
     #pragma hdrstop
#endif

#ifndef WX_PRECOMP
     #include <wx/wx.h>
#endif

class MyApp : public wxApp
{
	public:
		virtual bool OnInit();
};

#endif // APP_H

---------- main.cpp --------------
#include "main.h"

int idMenuQuit = wxNewId();
int idMenuAbout = wxNewId();

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
	EVT_MENU(idMenuQuit, MyFrame::OnQuit)
	EVT_MENU(idMenuAbout, MyFrame::OnAbout)
END_EVENT_TABLE()

MyFrame::MyFrame(wxFrame *frame, const wxString& title)
	: wxFrame(frame, -1, title)
{
	wxMenuBar* mbar = new wxMenuBar();
	wxMenu* fileMenu = new wxMenu(_(""));
	fileMenu->Append(idMenuQuit, _("&Quit\tAlt-F4"), _("Quit the  
application"));
	mbar->Append(fileMenu, _("&File"));

	wxMenu* helpMenu = new wxMenu(_(""));
	helpMenu->Append(idMenuAbout, _("&About\tF1"), _("Show info about this  
application"));
	mbar->Append(helpMenu, _("&Help"));

	SetMenuBar(mbar);

	// 5 Columns - lets try a BoxSizer
	wxFlexGridSizer* mainbox = new wxFlexGridSizer(1,3,0,0);
	SetSizer(mainbox);

	// Add a ScrolledWindow for holding the user interface panel(s)
	wxScrolledWindow* leftsc = new wxScrolledWindow(
                 this, wxID_ANY, wxDefaultPosition, wxDefaultSize,
                 wxVSCROLL, wxT("LeftScroll"));
     mainbox->Add(leftsc, 1,wxEXPAND,0);

     // Add a vertical box for the interface elements
     wxBoxSizer* leftbox = new wxBoxSizer(wxVERTICAL);
     leftsc->SetSizer(leftbox);

     // Add testbutton and some dummy sliders
     wxButton* test = new wxButton(leftsc, wxID_ANY,
             _("Test"));
     leftbox->Add(test,0,0,0);
     wxSlider* sl = NULL;
     for (int i=0; i<10; i++)
     {
         sl = new wxSlider(leftsc, wxID_ANY, 50, 0, 100,
             wxDefaultPosition, wxDefaultSize, wxSL_HORIZONTAL,
             wxDefaultValidator, wxT("Slider"));
         leftbox->Add(sl,0,0,0);
     }

     // Add Arrow
     wxButton* leftarrow = new wxButton(this, wxID_ANY,
             _("<"), wxDefaultPosition, wxDefaultSize, wxBU_EXACTFIT,
             wxDefaultValidator, wxT("leftbutton"));
     mainbox->Add(leftarrow,0,wxEXPAND,0);

     // Add main area
     wxTextCtrl* doc = new wxTextCtrl(this, wxID_ANY,
             _("The quick brown fox jumps over the lazy dog. "

               "The quick brown fox jumps over the lazy dog. "
               "The quick brown fox jumps over the lazy dog. "),
               wxDefaultPosition, wxDefaultSize, wxTE_MULTILINE,
               wxDefaultValidator, wxT("document"));
     mainbox->Add(doc, 1,wxEXPAND,0);
     mainbox->RemoveGrowableCol(0);
     mainbox->RemoveGrowableCol(1);
     mainbox->AddGrowableCol(2,1);

     Fit();
     leftsc->SetScrollbars(5,5,100,100,0,0,true);
