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"

How to show the parent widget hierarchy in child widget?

![alt text][1] [1]: /storage/temp/274570-捕获.png

I had derived a widget from a base user widget.Then I add a new Button on the derived widget,but it no working any way.The compile result showed that we can't have another widget hierarchy in derived widget.If we only have a widget hierarchy in parent class,how to show the parent widget hierarchy in the Hierarchy window?

Then I construct a new button in derived widget add to the base widget's canvas plane through derived widget's blueprint ,and it seem working.But Is there anyway edit the widget that derived from parent in derived widget's designer mode.Otherwise we just add and edit the widget through blueprint which is not visual.
