Re: RV: How to update the current position of a widget...

[Ignacio Nodal <inodal teleline es>]

The gdk_window_get_geometry didn't work. It returned nonsense values
such as xpos: 4 -- ypos: 24
But the window was created using
"gtk_widget_set_uposition(GTK_WIDGET(_pwindow),200,100);", so it should
have returned xpos: 200 -- ypos: 100.

I fixed it setting the new values by my own this way:

void ParamWindow::SetPosition(gint x, gint y)
{
  _pwindow->allocation.x = x;
  _pwindow->allocation.y = y;
  gtk_widget_set_uposition(GTK_WIDGET(_pwindow), x, y);
}

I don't think this is the best solution, but at least it works x)

Another newbie question hehehe. 
I've got a callback for a button's clicked event that creates a child
window. Of course, i only want to create ONE window, but when the window
is created.. if I continue clicking the button it creates everytime a
new window.How can I restrict this?
