ExtJs: Simple way to setup ‘All’ checkbox to reflect other checkboxes status across the row in a Grid Panel

Suppose you have a number of checkboxes (checkcolumn) for each row in a GridPanel and an ‘All’ checkbox to control & reflect the status of other checkboxes in the row, i.e.

  • Uncheck any box will also uncheck the ‘All’ checkbox
  • When all the checkboxes are checked, the ‘All’ checkbox is automatically checked

Sencha ExtJs Modern: How to Switch Off Compression in ‘Build & Emulate’

Although in Sencha Cmd, we can easily switch off compression by doing a Testing build. In ExtJs Modern framework, when we do a ‘Build & Emulate’, it compresses all the JS code anyway and there is no option to switch it off (Well, at least in Sencha Architect). This makes it hard to debug mobile applications when runs it on an Android emulator, especially using Chrome developer console to remote attach to the emulator.

I contacted the support, here is how you switch the compression off by adding highlighted lines to app.json as shown belown:

     "native": {
         "packager": "cordova",
         "compressor": null,
         "properties": {
            "build.compression": "",
            "enable.resource.compression": false
         },
         "cordova": {
            "config": {
               "id": "com.domain.MyApp",
               "name": "MyApp",
               "platforms": "android"
            }
         }
      }

After that, do a ‘Build & Emulate’ again. When you reconnect the Chrome developer console, you should see your own source code as well as ExtJs source.

<Directory /var/www>
    Options Indexes FollowSymLinks MultiViews
    # enable the .htaccess rewrites
    AllowOverride All
    Require all granted
</Directory>
