How to scroll the wxListBox one page ?

[manianis]

I'm using the MSW version of wxWidgets and the function GetScrollPageSize is not available. How to scroll manually by one page on MSW ?

[loptr]

could you provide some more information please?

in which context are you trying to use GetScrollPageSize?
where did you this method expect to be located?
for what object did you try to use the method?

maybe some code...?

I've a wxPanel with a wxTextCtrl and a wxListBox. The user can search the values in the wxListBox by typing in the wxTextCtrl.

I'm trying to make it intercat like the index search in CHM files.

Code: Select all

void ClientListPanel::OnClientTextCtrlKeyDown(wxKeyEvent& event)
{
	int nSel = m_clientList->GetSelection();
	wxString strSel;
	if (nSel == wxNOT_FOUND)
	{
		return;
	}
	if (event.GetKeyCode() == WXK_UP)
	{
		if (nSel > 0) nSel--;
		m_clientTextCtrl->SetEvtHandlerEnabled(false);
		strSel = m_clientList->GetString(nSel);
		m_clientList->SetSelection(nSel);
		m_clientTextCtrl->SetValue(strSel);
		m_clientTextCtrl->SetSelection(strSel.Len(), -1);
		m_clientTextCtrl->SetEvtHandlerEnabled(true);
	}
	else if (event.GetKeyCode() == WXK_DOWN)
	{
		if (nSel < m_clientList->GetCount()) nSel++;
		m_clientTextCtrl->SetEvtHandlerEnabled(false);
		strSel = m_clientList->GetString(nSel);
		m_clientList->SetSelection(nSel);
		m_clientTextCtrl->SetValue(strSel);
		m_clientTextCtrl->SetSelection(strSel.Len(), -1);
		m_clientTextCtrl->SetEvtHandlerEnabled(true);
	}
	else if (event.GetKeyCode() == WXK_PAGEUP)
	{
		// don't know how to handle it
	}
	else if (event.GetKeyCode() == WXK_PAGEDOWN)
	{
		// don't know how to handle it
	}
	else if (event.GetKeyCode() == WXK_RETURN)
	{
		NotifyUserSelected(nSel);
	}
}
