    XMLWordPrintable

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      windows_7

      Description

      ADDITIONAL SYSTEM INFORMATION :
      Windows 7, 64 Bit, AdoptJDK12.0.1+12 64 Bit

      A DESCRIPTION OF THE PROBLEM :
      GIF images in HTML tooltips are not rendered under circumstances when referenced from resource.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Add a tooltip text with html tooltip containing an image ("<img src=..." from resource or http) to a Swing control (e.g. JButton).
      Hovering over the button reveals tooltip with or without image under certain (unknown) circumstances.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The tooltips should show the images from the URL and the resource URL.
      But it does not.
      ACTUAL -
      Only some images in the tooltip are rendered.
      Tooltips do not render correct size.
