• How to declare the type in flow of a react redux component with defaultProps?

  Example1 below with type interference works but my attempts to declare the export to improve type checking fails (see Example2 and Example3).

  // @flow
  
  // react 16.3.1
  // redux 3.7.2
  // flow 0.67.0
  // flow-typed 2018-04-24
  
  import * as React from 'react'
  import { connect } from 'react-redux'
  
  type Props = {
      prop1: number,
      prop2: number,
  }
  
  type InjectedProps = {
  }
  
  class ExampleClass extends React.Component<Props & InjectedProps> {
      static defaultProps = { prop2: 1 }
  
      render() {
          return this.props.prop1 + this.props.prop2
      }
  }
  
  // works, but what is the type of Example1?
  export const Example1 = connect(null, null)(ExampleClass)
  
  // Cannot assign connect(...)(...) to Example2 because undefined [1] is incompatible with number [1] in property prop2 of type argument P [2].
  export const Example2: React.ComponentType<Props> = connect(null, null)(ExampleClass)
  
  // property prop1 is read-only in Props [1] but writable in object type [2] in type argument P [3].
  // property prop2 is read-only in Props [1] but writable in object type [2] in type argument P [3].
  export const Example3: React.ComponentType<React.ElementConfig<React.ComponentType<Props>>> = connect(null, null)(ExampleClass)
  
• mouseout event not always trigger

  I use google maps api to create map with markers. On marker hover (mouseover event) I show info window and change marker icon, on unhover (mouseout event) I close info window and change marker icon. But sometimes mouseout event not triggers when I move the cursor quickly and info window stays open.

  google.maps.Marker doesn't support events: mouseenter and mouseleave.

  GIF that shows my problem

  How I can solve my problem?

  Here is my code:

              marker = new google.maps.Marker({
                  position: {lat: stop.gps_lat, lng: stop.gps_long},
                  map: map,
                 icon: icon
              });
  
              marker.onHover = (function(infoWindow, marker) {
                  return function() {
                      infoWindow.open(map);
                      marker.setIcon(selectedIcon);
                  };
              })(infoWindow, marker);
  
              marker.onUnhover = (function(infoWindow, marker) {
                  return function() {
                      infoWindow.close();
                      marker.setIcon(icon);
                  };
              })(infoWindow, marker);
  
  
              marker.addListener('mouseover', marker.onHover);
              marker.addListener('mouseout', marker.onUnhover);
  
• can Map store a class? "in this environment the sources for assign must be an object"

  I am trying to create a map of classes in react native. I am using Mobx as the store.

  Here is the code:

  getCoinData() {
      if (this.perCoinData.size > 0) return;
      this.pieData.forEach((value, key, map) => {
          const [ exchange, name, currency ] = value._id.split('-');
          this.perCoinData.set(
              key,
              new Coin(('_id': value._id), exchange, name, currency)
          );
      });
  }
  

  pieData is another Map which contains a string key and an object value. Coin is the class which I want to store instances of in the Map object. However, when the function runs, I get the error:

  In this environment the sources for assign MUST be an object. This error is a performance optimization and not spec compliant.

  The reason I want it in a Map is because I want all of the key/values to be observable and I don't know the length of the object. How can I achieve this?
• multi selection of rows in multiple page is not working in jqgrid?

• load image in a modal before running a jQuery

  I have been recently working on zooming in and zooming out of the images. The plugin I use guillotine, works perfectly apart from one little detail.

  I am trying to get it working on the website that has been done in angularJS and displays a modal where the image resides. The specs of the plugin say that the image has to be loaded to get the plugin working properly. And this is my issue.

  I have tried different jQuery/js events to make sure that the picture I am interested in is loaded before the plugin's function is fired. However, nothing seems to work.

  Do you have any ideas how can I verify if the specific image that I am looking for in a modal window has been loaded properly before the jQuery with the plugin functions fires?

  Thanks a lot!
