问题 I have a QWidget and i need to do some actions (refresh a picture in widget) when resize event ends. How can i catch this action? I need to catch moment when user ENDs all his resize actions by releasing mouse button. It is not a good practice in my application to refresh image every pixel resized.

问题 This is my first post on SO, however a lot of Googling has led me here over the years. I am trying to detect brightness changes on my laptop using a set of tools called Windows Management Instrumentation (WMI), particularly an event class called WmiMonitorBrightnessEvent and a watch_for listener. The use of the latter is described here: http://timgolden.me.uk/python/wmi/wmi.html#wmi._wmi_namespace.watch_for c = wmi.WMI () watcher = c.watch_for ( notification_type="Creation", wmi_class="Win32

问题 I have an event handling code that reads Linux's /dev/input/ for my touchpad and prints result on the basis of which button is pressed/released. Although. as of now my code is waiting on a button press while running on terminal. My next step is to run this event handling thread along with another thread (not event based). If I continue handling event by reading input at terminal, I will not be able to execute other threads as a part of my main() as main() keeps on waiting for the button press

问题 I have a loop that generates let's say 20 divs. Each div is an object from my local objects array. Here's the code: <div *ngFor="let item of userInventory" class="col-2 c-pointer" (click)="addItemToArray(item)"> <img src="{{item.image}}" class="img-fluid"/> <span class="d-block">{{item.name}}</span> </div> When a user clicks on the div(item) it will add the item to an array: addItemToArray(item) { this.itemsToSend.push(item); item.isAdded = true; } The user under no circumstances is allowed

Since you didn't indicate what that other library is, here's a native solution: Example: http://jsfiddle.net
