c++ - Subclass of QGraphicsLayoutItem for stretchers? -

-

QGraphicsLayout के विशेषज्ञ (जैसे QGraphicsLinearLayout) में एक सम्मिलित स्ट्रेच विधि शामिल है।

QGraphicsLinearLayout किस प्रकार का ऑब्जेक्ट करते हैं :: डालेंस्ट्रेच विधि लेआउट द्वारा प्रबंधित मदों की सूची में डालें? बेहतर पूछे जाने पर: QGraphicsLayout :: itemAt विधि द्वारा किस प्रकार की ऑब्जेक्ट वापस की जाती है जब एक स्टॉप की स्थिति के लिए बुलाया जाता है?

मैंने कभी इसकी जांच नहीं की है, इसलिए मैं नहीं जानता, लेकिन अगर आप वास्तव में उत्सुक हैं, तो आप उस स्थिति में एक वस्तु के लिए पूछ सकते हैं। मान लें कि यह NULL वापस नहीं लौटाता है, तब आप मेटा जानकारी के माध्यम से अपना काम कर सकते हैं और इसके बारे में बहुत कुछ जानकारी पा सकते हैं।

मुझे आश्चर्य नहीं होगा हालांकि, अगर यह कोई स्टॉक QWidget था (खाली, कोई चित्र नहीं)।

Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
