c++ - Not able to set the geometry in QT -


I set the widget to set the coordinates of setGemometry () I am using But when I delete some widget and delete it from the main layout, then it is not fully capable of setting geometry. I am using KeyReleaseEvent () , that is, when I am pressing key D, some widgets should be removed and it should set geometry to a specific location when I first press it The effect is not seen, but the widgets are removed and when I press it for the second time it is set properly. 

  void mywindow :: popupwindow () {If (stack1-> current index () == 0) {stack3-> Hide (); MainLayout-> AddWidget (stack2); Stack2-> Show (); Stack2-> SetFixedSize (400,200); This- & gt; SetGeometry (100,400,900,200); } If (Stack 1-> Current Index () == 1) {stack2-> Hide (); MainLayout-> AddWidget (stack3); Stack3- & gt; Show (); Stack3- & gt; SetFixedSize (400,200); This- & gt; SetGeometry (100,400,900,200); }} Zero mywindow :: deleteWindow () {mainLayout-> RemoveWidget (stack2); MainLayout-> RemoveWidget (stack3); Stack2-> Hide (); Stack3- & gt; Hide (); This- & gt; SetGeometry (100,400,500,200); }   
  popup window ()  linked to a  KeyReleasedEvent ()  and  deleteWindow ()  The other key is  
 basic window  
  after pressing the key and calling popworn ()   
  window to delete after de-pressing D key ()  Second time by pressing the D key and numeric 1: Basic window Finger 2: Press the popup window () After the call, call for delivery for 3 minutes   
  Time Fug 4: Again, after calling again window () for the second time   
  
 
 
 After deleting widgets, if you want to resize everything well, you should change the  adjustSize () Call .  
 Apart from this, the widget size on a stacked widget can affect the width and height of the end that ends in your window.  
 Hope that helps.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
