From the Tk::focus POD:

$widget->focusForce Sets the focus of $widget's display to $widget, even if the + appli- cation doesn't currently have the input focus for the displ +ay. This command should be used sparingly, if at all. In norma +l usage, an application should not claim the focus for itself; inst +ead, it should wait for the window manager to give it the focus.

I've found only one case where focusForce was required to get focus back to one of my windows, and that was after a call to getOpenFile from a composite widget. I'm still not sure if focusForce was required because of something I was doing wrong or a focus bug introduced by getOpenFile (I suspect the former).

If raising a window doesn't cause the window manager to give it focus, then $widget->focus should be sufficient.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
