c++ - Initialisation, Copy constructor and assignment -

-

मेरे पास एक जटिल वर्ग है और मुख्य बात यह है: 

  int main () {जटिल सी 1; जटिल सी 2 = सी 1; जटिल सी 3 (सी 1); जटिल सी 4; सी 4 = c1; }

काम करने के लिए या सभी इन स्टेटमेंटों को जटिल कक्षा में किस कंस्ट्रक्चर की आवश्यकता होगी? और, अतिभारित असाइनमेंट या कॉपी कन्स्ट्रक्टर का उपयोग निम्न में किया जाएगा: 

  जटिल c2 = c1; जटिल सी 3 (सी 1);  

  जटिल c1;

डिफ़ॉल्ट c-tor। 

  जटिल c2 = c1;

कॉपी c-tor। 

  जटिल c3 (c1);

कॉपी c-tor। 

  जटिल c4;

डिफ़ॉल्ट c-tor। 

  c4 = c1;

असाइनमेंट ऑपरेटर।

डिफॉल्ट कन्स्ट्रक्टर को कंपाइलर द्वारा परिभाषित किया गया है, अगर आपके पास कोई अन्य कन्स्ट्रक्टर परिभाषित नहीं है (या आप बिना मापदंडों वाले कन्स्ट्रक्टर को परिभाषित कर सकते हैं)।

< पी> प्रतिलिपि कन्स्ट्रक्टर और असाइनमेंट ऑपरेटर को संकलक द्वारा परिभाषित किया जाता है, यदि आप परिभाषित नहीं करते हैं।

I am working on a page that will create a team. I just want to create a selection box which will list all the users of all the users.

java - How to drag a JavaFX node and detect a drop event outside the JavaFX Windows? -

-
I am implementing a tabkin that can be separated from the JavaFX window. When the tab panel is pulled out of the window where it came from, I have to create a new window and the tab to be placed in that window. I have already applied some methods using drag gestures, drag the tab between the existing window. However, when I'm taking a mouse out of javax sequences, I'm not able to get any mouse events or drag events. Is this something possible? You can listen to a mouse release incident on the appropriate node (like the graphic of the tab). Check the screen coordinates using MouseEvent.getScreenX () and MouseEvent.getScreenY () and see if they are out of the current window. If they do, create a new window, view and tab panel; Remove the tab from the current tab panel and place it in a new location. There is no fundamental example with no frills (for example, a user does not indicate that the dragging is happening), but you should consider this: import Please ...
