How to get size of wx wxHtmlWindow

Hi

I have dialog that contains only wxHtmlWindow. In a dialog constructor I load html page to this wxHtmlWindow, and I want that window have normal size when appear. So, wxHtmlWindow control should show all html page without scroll bars and blank field and winwow's size should be == size of wxHtmlWindow control.

Problem is I can't force wxHtmlWindow to get real size of loaded html. Any ideas?

try this:

Code: Select all

wxSize vs = html_window->GetVirtualSize();
SetClientSize(vs);  // For the parent

This does not work in Create(). So, I have created timer and resize window after 10 ms... But there is still some problems with window visible and size - GetVirtualSize() returns correct width but incorect height. I'll try to fix it in few after week end.

Thanks for help.

I just faced a very similar problem. I am using an instance wxHtmlWindow to show a super tool tip (like Excel), and I want no scroll bars and for it to be just large enough to display the contents. There is no predetermined way of doing that

, but this is how I got the result I wanted

. Works perfectly!

Code: Select all

   //There is no way to get the perfect height for the window.
   //So we set it to something too small for starters:
   int ySize = 50;
   int xSize = 200;
   mywxHTML->SetSize(xSize, ySize);

   //Now if we got a vertical scroll bar, then make the window taller,
   //to get rid of the scroll bar:
   int vxSize=0;
   int vySize=0;
   mywxHTML->GetVirtualSize(&vxSize, &vySize);
   if (vySize > ySize)
      {
      mywxHTML->SetSize(xSize, vySize);
      }

   //Now reset the text to make it redo the layout and sizes:
   wxString wxEmpty;
   mywxHTML->SetPage(wxEmpty);
   mywxHTML->SetPage(html2);

   //Now get the final size, which may have reduced more since the scroll bar
   //is now gone.
   wxHtmlContainerCell* cell = mywxHTML->GetInternalRepresentation();
   if (cell)
      {
      int height = cell->GetHeight();
      mywxHTML->SetSize(xSize, height + oborder + oborder);
      }

   //Show it:
   mywxHTML->Show(true);

   //Make sure it is seen:
   mywxHTML->Raise();

To get a nice rectangle around the outer edges of the window, I also did this:

Code: Select all

mywxHTML->SetBorders(1);

And then my tip contents is wrapped around a matrix with a border but with the cell spacing set to zero.

Code: Select all

<body bgcolor="xxx background colour goes here xxx">
<table width="100%" border="1" cellspacing="0" cellpadding="8"><tr><td>
xxx tip text HTML goes here xxx
</td></tr></table>
</body>

The end result is you get an HTML window that is just big enough to show its contents, no scroll bars, and it has a nice border line around it.
