<!-- DIV {margin:0px;}-->Hi!!

I'm trying to use a wxScrolledWindow with a wxSimpleHtmlListBox inside, but the problem is that when I change the wxScrolledWindow 's size the HScrollBar set to disabled.

when I change the size of the frame the wxScrolledWindow.GetClientSize(), the wxScrolledWindow.GetVirtualSize() and the wxSimpleHtmlListBox.GetSize() return the same values, hence there is no need for a scrollbar. But the wxSimpleHtmlListBox.GetSize() should be bigger because of it´s contents, and this should enable the scrollbar (because I set wxScrolledWindow´s virtualsize to this dimension).

Could you help me to fix it??



In the constructor I have:

wxFrame *pframe = this;
pframe->Create(NULL,wxID_ANY,"My Frame");

pframe->SetSizer(psizerframe);

pPanel_ = new wxPanel(pframe, wxID_PANEL1);

psizerframe->Add(pPanel_, 1, wxEXPAND);

pPanel_->SetSizer(psizerpanel);

pScrollWindow_ = new wxScrolledWindow(pPanel_, wxID_SCROLLWINDOW);

psizerpanel->Add(pScrollWindow_,1,wxEXPAND);

pScrollWindow_->SetSizer(psizerscroll);

pHtmlList_ = new wxSimpleHtmlListBox();

const wxString choices[] = {"Elemento_1", "Elemento_2_Nombre_corto.",
"Elemento_3_Nombre_largo_aldfaldsfladfladkflasdfkalsdfkadlfkalkjfads."};

pHtmlList_->Create(pScrollWindow_, wxID_HTMLSIMPLELIST, wxDefaultPosition, wxDefaultSize, 3, choices);

psizerscroll->Add(pHtmlList_,1,wxEXPAND);



In the OnResize() I'm doing:

m_ScrollWindow->SetVirtualSize(m_HtmlList->GetSize());


Regards.
Alejandro

Hi for everyone!!

I managed to get the scrollbar enable, but I can't understand why. What I did is to set the default size for the wxSimpleHtmlListBox.

pHtmlList_->Create(pScrollWindow_, wxID_HTMLSIMPLELIST, wxDefaultPosition, wxSize(500, 50), 3, choices);
I would be grateful if someone explain me this.


Regards.
Alejandro

Asunto: Re: wxSimpleHtmlListBox size smaller than content requires

I forgot to said, that I use:

pScrollWindow_->SetScrollRate(10, 0);
