QUESTION
Mey be it is simple, but I'm new in frontend. I have a page component. And I need to fetch data before component calculated.
...ANSWER
Answered 2021-Apr-10 at 17:31if you have difficulties with timings and async tasks, why don't you use async/await?
you want to wait
in a async
function (for example calling a backend for data) till the data is fetched. then you want to manipulate/delete/change/add, do what ever you want with that data and display the result on screen.
the point is, Vue is a reactive Framework, which means it rerenders (if the setup is correct made) the content by itself after what ever calculation is finished. so don't worry about something like that.
to be honest, the question is asked really weird. and your code is hard to read. sometimes moving two steps back and try a other way isn't false as well.

I wrote a programm reading specific messages from gmail. After reading and analysing I want to delete them. However, I can't get it to work. I use the following code:
...ANSWER
Answered 2020-Oct-05 at 15:13For GMail you need to move them trash (UID MOVE x "[Gmail/Trash]"
). Watch out for localization of the folder.
Gmail considers the \Deleted flag to be removing the label from that message, which means deleting the Inbox label is effectively the same as archiving the message.

ANSWER
Answered 2019-Oct-15 at 19:06how to compute ortho parameters for saving original view size of object/position of camera?
At orthographic projection the 3 dimensional scene is parallel projection to the 2 dimensional viewport.
This means that the objects, which are projected on the viewport always have the same size, independent of their depth (distance to the camera).
The perspective projection describes the mapping from 3D points in the world as they are seen from of a pinhole camera, to 2D points of the viewport.
This means an object which is projected on the viewport becomes smaller, by its depth.
If you switch form perspective to orthographic projection only the objects in 1 plane, which is planar (parallel) to the viepwort, and keeps its depth. Note, a plane is 2 dimensional and has no "depth". This cause that a 3 dimensional object never can "look" the same, when the projection is switched. But a 2 dimensional billboard can keep it's size.
The ration of depth an size at perspective projection is linear and can be calculated. It depends on the field of view angle only:
