Changes for version 1.12

  • This is a maintenance release of Tk-JComboBox that addresses an issue with the -popupcreate callback option. In addition, I've updated some test cases, added an examples directory, and updated some of the Pod files. There is a potential backward compatibility issue with this release (the -popupcreate option), but there is no major new functionality (At least one new option may be coming in the next release...)
    • Issue: jdtoronto posted a bug report on the Perlmonks site. http://perlmonks.org/?node_id=573624. He was attempting to use the popupcreate option to modify the JComboBox each time the Popup was triggered. In version 1.11 and for at least the past few versions, registering a callback to this option meant that you were assuming responsibility for configuring the height/width and positioning of the JCombobox, which can be a pain.
      • Resolution: I decided that this was too big a pain to pass on to users, and modified the option so that the physical configuration occurs outside of this callback. -popupmodify can still be used to override the layout properties if needed. The result is that popupcreate is simpler to implement (it was mostly provided as a means to alter the list item contents of the JComboBox). Documentation, and test cases were adjusted accordingly, plus an example was provided in the new examples directory that demonstrates the option in action.
    • After conversation with Fred Jan, I reconsidered the implementation of the -textvariable option. JComboBox goes a bit further than some other widgets and heavily controls -textvariable use. I've decided to leave it as is for now, but to hold onto the correspondance and possibly revisit it in the future. No changes aside from a tweak to the docs.
    • Took another pass through the JComboBox docs to update several links that were incorrect, and fix some wording here and there.
