Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[UMG] Weird Focus with Touch

I start a new project and show a Widget with a Button and Combobox. The button events are linked as such:

alt text

This is what happens if it is pressed with touch:

Events are called twice when used with touch. When you click a combobox it opens AND closes the itemlist making it unusable.

The interesting part is, if you press the button, drag off the button and release, the click event is not called (as it should) and the combobox can be opened.

It seems to me that there is a problem with the focus when using touch. Any ideas?
