It is a hyper-legible collection of 223 icons with a tiny footprint—ready to use with Bootstrap and Foundation. [View the collection](http://useiconic.com/open#icons) 5 | 6 | 7 | 8 | ## What's in Open Iconic? 9 | 10 | * 223 icons designed to be legible down to 8 pixels 11 | * Super-light SVG files - 61.8 for the entire set 12 | * SVG sprite—the modern replacement for icon fonts 13 | * Webfont (EOT, OTF, SVG, TTF, WOFF), PNG and WebP formats 14 | * Webfont stylesheets (including versions for Bootstrap and Foundation) in CSS, LESS, SCSS and Stylus formats 15 | * PNG and WebP raster images in 8px, 16px, 24px, 32px, 48px and 64px. 16 | 17 | 18 | ## Getting Started 19 | 20 | #### For code samples and everything else you need to get started with Open Iconic, check out our [Icons](http://useiconic.com/open#icons) and [Reference](http://useiconic.com/open#reference) sections. 21 | 22 | ### General Usage 23 | 24 | #### Using Open Iconic's SVGs 25 | 26 | We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute). 27 | 28 | ``` 29 | icon name 30 | ``` 31 | 32 | #### Using Open Iconic's SVG Sprite 33 | 34 | Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack. 35 | 36 | Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `` *tag and a unique class name for each different icon in the* `` *tag.* 37 | 38 | ``` 39 | 40 | 41 | 42 | ``` 43 | 44 | Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `` tag with equal width and height dimensions. 45 | 46 | ``` 47 | .icon { 48 | width: 16px; 49 | height: 16px; 50 | } 51 | ``` 52 | 53 | Coloring icons is even easier. All you need to do is set the `fill` rule on the `` tag. 54 | 55 | ``` 56 | .icon-account-login { 57 | fill: #f00; 58 | } 59 | ``` 60 | 61 | To learn more about SVG Sprites, read [Chris Coyier's guide](http://css-tricks.com/svg-sprites-use-better-icon-fonts/). 62 | 63 | #### Using Open Iconic's Icon Font... 64 | 65 | 66 | ##### …with Bootstrap 67 | 68 | You can find our Bootstrap stylesheets in `font/css/open-iconic-bootstrap.{css, less, scss, styl}` 69 | 70 | 71 | ``` 72 | 73 | ``` 74 | 75 | 76 | ``` 77 | 78 | ``` 79 | 80 | ##### …with Foundation 81 | 82 | You can find our Foundation stylesheets in `font/css/open-iconic-foundation.{css, less, scss, styl}` 83 | 84 | ``` 85 | 86 | ``` 87 | 88 | 89 | ``` 90 | 91 | ``` 92 | 93 | ##### …on its own 94 | 95 | You can find our default stylesheets in `font/css/open-iconic.{css, less, scss, styl}` 96 | 97 | ``` 98 | 99 | ``` 100 | 101 | ``` 102 | 103 | ``` 104 | 105 | 106 | ## License 107 | 108 | ### Icons 109 | 110 | All code (including SVG markup) is under the [MIT License](http://opensource.org/licenses/MIT). 111 | 112 | ### Fonts 113 | 114 | All fonts are under the [SIL Licensed](http://scripts.sil.org/cms/scripts/page.php?item_id=OFL_web). 115 | -------------------------------------------------------------------------------- /samples/CodeBehind/wwwroot/css/open-iconic/FONT-LICENSE: -------------------------------------------------------------------------------- 1 | SIL OPEN FONT LICENSE Version 1.1 2 | 3 | Copyright (c) 2014 Waybury 4 | 5 | PREAMBLE 6 | The goals of the Open Font License (OFL) are to stimulate worldwide 7 | development of collaborative font projects, to support the font creation 8 | efforts of academic and linguistic communities, and to provide a free and 9 | open framework in which fonts may be shared and improved in partnership 10 | with others. 11 | 12 | The OFL allows the licensed fonts to be used, studied, modified and 13 | redistributed freely as long as they are not sold by themselves.

In event aggregator pattern you have message/event publishers and subscribers. In the case of Blazor, component can publish its events and other component(s) can react to those events. 8 | 9 | [![NuGet](https://img.shields.io/nuget/v/EventAggregator.Blazor.svg)](https://www.nuget.org/packages/EventAggregator.Blazor/) 10 | 11 | ### Note: 12 | 13 | Blazor.EventAggregator is completely based on the work done in Caliburn.Micro. The source code was copied from it and then altered to work with Blazor. 14 | 15 | Also note that the library has only been tested with the server-side version of Blazor. There's no known issues with the WebAssembly-version of Blazor. 16 | 17 | ## Getting Started 18 | 19 | First register EventAggregator in app’s ConfigureServices: 20 | ``` 21 | public void ConfigureServices(IServiceCollection services) 22 | { 23 | services.AddEventAggregator(); 24 | } 25 | ``` 26 | 27 | The rest depends on if you’re using components with code-behinds (inheritance) or without inheritance. The following guidance is for code-behind scenarios. 28 | 29 | ### Creating the publisher 30 | 31 | To create an event publishing component, first inject IEventAggregator: 32 | 33 | ``` 34 | [Inject] 35 | private IEventAggregator _eventAggregator { get; set; } 36 | ``` 37 | 38 | Then publish the message when something interesting happens: 39 | 40 | ``` 41 | await _eventAggregator.PublishAsync(new CounterIncreasedMessage()); 42 | ``` 43 | 44 | Here’s a full example of a publisher: 45 | ``` 46 | public class CounterComponent : ComponentBase 47 | { 48 | [Inject] 49 | private IEventAggregator _eventAggregator { get; set; } 50 | 51 | public int currentCount = 0; 52 | 53 | public async Task IncrementCountAsync() 54 | { 55 | currentCount++; 56 | await _eventAggregator.PublishAsync(new CounterIncreasedMessage()); 57 | } 58 | } 59 | 60 | public class CounterIncreasedMessage 61 | { 62 | } 63 | ``` 64 | 65 | ### Creating the subscriber 66 | 67 | To create an event subscriber, also start by injecting IEventAggregator: 68 | 69 | ``` 70 | [Inject] 71 | private IEventAggregator _eventAggregator { get; set; } 72 | ``` 73 | Then make sure to add and implement the IHandle interface for all the event’s your component is interested in: 74 | 75 | ``` 76 | public class CounterListenerComponent : ComponentBase, IHandle 77 | ... 78 | public Task HandleAsync(CounterIncreasedMessage message) 79 | { 80 | currentCount += 1; 81 | return Task.CompletedTask; 82 | } 83 | ``` 84 | 85 | Here’s full example of a subscriber: 86 | 87 | ``` 88 | public class CounterListenerComponent : ComponentBase, IHandle 89 | { 90 | [Inject] 91 | private IEventAggregator _eventAggregator { get; set; } 92 | 93 | public int currentCount = 0; 94 | 95 | protected override void OnInit() 96 | { 97 | _eventAggregator.Subscribe(this); 98 | } 99 | 100 | public Task HandleAsync(CounterIncreasedMessage message) 101 | { 102 | currentCount += 1; 103 | return Task.CompletedTask; 104 | } 105 | } 106 | ``` 107 | 108 | ## Note about auto refresh 109 | 110 | The library can try to automatically call subscriber component's StateHasChanged after it has handled the event. By default this functionality is disabled. You can enable it through options: 111 | 112 | ``` 113 | services.AddEventAggregator(options => options.AutoRefresh = true); 114 | ``` 115 | 116 | Auto refresh is based on reflection and it assumes that the subscriber inherits from ComponentBase. 117 | 118 | ## Samples 119 | 120 | The project site contains a full working sample of the code-behind model in the samples-folder. 121 | 122 | ## Requirements 123 | The library has been developed and tested using the following tools: 124 | 125 | * .NET Core 3.1 126 | * Visual Studio 2019 127 | 128 | ## Acknowledgements 129 | Work is based on the code available in Caliburn.Micro. 130 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | ## Ignore Visual Studio temporary files, build results, and 2 | ## files generated by popular Visual Studio add-ons. 3 | ## 4 | ## Get latest from https://github.com/github/gitignore/blob/master/VisualStudio.gitignore 5 | 6 | # User-specific files 7 | *.suo 8 | *.user 9 | *.userosscache 10 | *.sln.docstates 11 | 12 | # User-specific files (MonoDevelop/Xamarin Studio) 13 | *.userprefs 14 | 15 | # Build results 16 | [Dd]ebug/ 17 | [Dd]ebugPublic/ 18 | [Rr]elease/ 19 | [Rr]eleases/ 20 | x64/ 21 | x86/ 22 | bld/ 23 | [Bb]in/ 24 | [Oo]bj/ 25 | [Ll]og/ 26 | 27 | # Visual Studio 2015 cache/options directory 28 | .vs/ 29 | # Uncomment if you have tasks that create the project's static files in wwwroot 30 | #wwwroot/ 31 | 32 | # MSTest test Results 33 | [Tt]est[Rr]esult*/ 34 | [Bb]uild[Ll]og.* 35 | 36 | # NUNIT 37 | *.VisualState.xml 38 | TestResult.xml 39 | 40 | # Build Results of an ATL Project 41 | [Dd]ebugPS/ 42 | [Rr]eleasePS/ 43 | dlldata.c 44 | 45 | # .NET Core 46 | project.lock.json 47 | project.fragment.lock.json 48 | artifacts/ 49 | **/Properties/launchSettings.json 50 | 51 | *_i.c 52 | *_p.c 53 | *_i.h 54 | *.ilk 55 | *.meta 56 | *.obj 57 | *.pch 58 | *.pdb 59 | *.pgc 60 | *.pgd 61 | *.rsp 62 | *.sbr 63 | *.tlb 64 | *.tli 65 | *.tlh 66 | *.tmp 67 | *.tmp_proj 68 | *.log 69 | *.vspscc 70 | *.vssscc 71 | .builds 72 | *.pidb 73 | *.svclog 74 | *.scc 75 | 76 | # Chutzpah Test files 77 | _Chutzpah* 78 | 79 | # Visual C++ cache files 80 | ipch/ 81 | *.aps 82 | *.ncb 83 | *.opendb 84 | *.opensdf 85 | *.sdf 86 | *.cachefile 87 | *.VC.db 88 | *.VC.VC.opendb 89 | 90 | # Visual Studio profiler 91 | *.psess 92 | *.vsp 93 | *.vspx 94 | *.sap 95 | 96 | # TFS 2012 Local Workspace 97 | $tf/ 98 | 99 | # Guidance Automation Toolkit 100 | *.gpState 101 | 102 | # ReSharper is a .NET coding add-in 103 | _ReSharper*/ 104 | *.[Rr]e[Ss]harper 105 | *.DotSettings.user 106 | 107 | # JustCode is a .NET coding add-in 108 | .JustCode 109 | 110 | # TeamCity is a build add-in 111 | _TeamCity* 112 | 113 | # DotCover is a Code Coverage Tool 114 | *.dotCover 115 | 116 | # Visual Studio code coverage results 117 | *.coverage 118 | *.coveragexml 119 | 120 | # NCrunch 121 | _NCrunch_* 122 | .*crunch*.local.xml 123 | nCrunchTemp_* 124 | 125 | # MightyMoose 126 | *.mm.* 127 | AutoTest.Net/ 128 | 129 | # Web workbench (sass) 130 | .sass-cache/ 131 | 132 | # Installshield output folder 133 | [Ee]xpress/ 134 | 135 | # DocProject is a documentation generator add-in 136 | DocProject/buildhelp/ 137 | DocProject/Help/*.HxT 138 | DocProject/Help/*.HxC 139 | DocProject/Help/*.hhc 140 | DocProject/Help/*.hhk 141 | DocProject/Help/*.hhp 142 | DocProject/Help/Html2 143 | DocProject/Help/html 144 | 145 | # Click-Once directory 146 | publish/ 147 | 148 | # Publish Web Output 149 | *.[Pp]ublish.xml 150 | *.azurePubxml 151 | # TODO: Comment the next line if you want to checkin your web deploy settings 152 | # but database connection strings (with potential passwords) will be unencrypted 153 | *.pubxml 154 | *.publishproj 155 | 156 | # Microsoft Azure Web App publish settings.
