Try with `zig build`. 73 | 74 | ## Contributing 75 | 76 | This library is in a early state and is very WIP. Still, feel free to contribute with PRs, or use it. Just don't assume a stable API. -------------------------------------------------------------------------------- /Sdk.zig: -------------------------------------------------------------------------------- 1 | const std = @import("std");

-------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | Microsoft.Web.WebView2.WinForms 5 | 6 | 7 | 8 | 9 | This class is a bundle of the most common parameters used to create a . 10 | Its main purpose is to be set to in order to customize the environment used by a during implicit initialization. 11 | 12 | 13 | This class isn't intended to contain all possible environment customization options. 14 | If you need complete control over the environment used by a WebView2 control then you'll need to initialize the control explicitly by 15 | creating your own environment with and passing it to 16 | *before* you set the property to anything. 17 | See the class documentation for an initialization overview. 18 | 19 | 20 | 21 | 22 | Creates a new instance of with default data for all properties. 23 | 24 | 25 | 26 | 27 | Gets or sets the value to pass as the browserExecutableFolder parameter of when creating an environment with this instance. 28 | 29 | 30 | 31 | 32 | Gets or sets the value to pass as the userDataFolder parameter of when creating an environment with this instance. 33 | 34 | 35 | 36 | 37 | Gets or sets the value to use for the Language property of the CoreWebView2EnvironmentOptions parameter passed to when creating an environment with this instance. 38 | 39 | 40 | 41 | 42 | Create a using the current values of this instance's properties. 43 | 44 | A task which will provide the created environment on completion. 45 | 46 | As long as no other properties on this instance are changed, repeated calls to this method will return the same task/environment as earlier calls. 47 | If some other property is changed then the next call to this method will return a different task/environment. 48 | 49 | 50 | 51 | 52 | Control to embed WebView2 in WinForms. 53 | 54 | 55 | 56 | 57 | Create a new WebView2 WinForms control. 58 | After construction the property is null. 59 | Call to initialize the underlying . 60 | 61 | 62 | This control is effectively a wrapper around the WebView2 COM API, which you can find documentation for here: https://aka.ms/webview2 63 | You can directly access the underlying ICoreWebView2 interface and all of its functionality by accessing the property. 64 | Some of the most common COM functionality is also accessible directly through wrapper methods/properties/events on the control. 65 | 66 | Upon creation, the control's CoreWebView2 property will be null. 67 | This is because creating the CoreWebView2 is an expensive operation which involves things like launching Edge browser processes. 68 | There are two ways to cause the CoreWebView2 to be created: 69 | 1) Call the method. This is referred to as explicit initialization. 70 | 2) Set the property. This is referred to as implicit initialization. 71 | Either option will start initialization in the background and return back to the caller without waiting for it to finish. 72 | To specify options regarding the initialization process, either pass your own to EnsureCoreWebView2Async or set the control's property prior to initialization. 73 | 74 | When initialization has finished (regardless of how it was triggered) then the following things will occur, in this order: 75 | 1) The control's event will be invoked. If you need to perform one time setup operations on the CoreWebView2 prior to its use then you should do so in a handler for that event. 76 | 2) If a Uri has been set to the property then the control will start navigating to it in the background (i.e. these steps will continue without waiting for the navigation to finish). 77 | 3) The Task returned from will complete. 78 | 79 | For more details about any of the methods/properties/events involved in the initialization process, see its specific documentation. 80 | 81 | Accelerator key presses (e.g. Ctrl+P) that occur within the control will 82 | fire standard key press events such as OnKeyDown. You can suppress the 83 | control's default implementation of an accelerator key press (e.g. 84 | printing, in the case of Ctrl+P) by setting the Handled property of its 85 | EventArgs to true. Also note that the underlying browser process is 86 | blocked while these handlers execute, so: 87 | 88 | 89 | You should avoid doing a lot of work in these handlers. 90 | 91 | 92 | Some of the WebView2 and CoreWebView2 APIs may throw errors if 93 | invoked within these handlers due to being unable to communicate with 94 | the browser process. 95 | 96 | 97 | If you need to do a lot of work and/or invoke WebView2 APIs in response to 98 | accelerator keys then consider kicking off a background task or queuing 99 | the work for later execution on the UI thread. 100 | 101 | 102 | 103 | 104 | Cleans up any resources being used. 105 | 106 | true if managed resources should be disposed; otherwise, false. 107 | 108 | 109 | 110 | Overrides the base OnPaint event to have custom actions 111 | in designer mode 112 | 113 | The graphics devices which is the source 114 | 115 | 116 | 117 | Overrides the base WndProc events to handle specific window messages. 118 | 119 | The Message object containing the HWND window message and parameters 120 | 121 | 122 | 123 | Gets or sets a bag of options which are used during initialization of the control's . 124 | This property cannot be modified (an exception will be thrown) after initialization of the control's CoreWebView2 has started. 125 | 126 | Thrown if initialization of the control's CoreWebView2 has already started. 127 | 128 | 129 | 130 | Explicitly trigger initialization of the control's . 131 | 132 | 133 | A pre-created that should be used to create the . 134 | Creating your own environment gives you control over several options that affect how the is initialized. 135 | If you pass null (the default value) then a default environment will be created and used automatically. 136 | 137 | 138 | A Task that represents the background initialization process. 139 | When the task completes then the property will be available for use (i.e. non-null). 140 | Note that the control's event will be invoked before the task completes 141 | or on exceptions. 142 | 143 | 144 | Calling this method additional times will have no effect (any specified environment is ignored) and return the same Task as the first call. 145 | Calling this method after initialization has been implicitly triggered by setting the property will have no effect (any specified environment is ignored) and simply return a Task representing that initialization already in progress. 146 | 147 | Thrown when invoked from non-UI thread. 148 | Thrown when this instance of is already disposed. 149 | Thrown when browser process has unexpectedly and left this control in an invalid state.

This is referred to as explicit initialization. 70 | 2) Set the property. This is referred to as implicit initialization. 71 | Either option will start initialization in the background and return back to the caller without waiting for it to finish. 72 | To specify options regarding the initialization process, either pass your own to EnsureCoreWebView2Async or set the control's property prior to initialization. 73 | 74 | When initialization has finished (regardless of how it was triggered) then the following things will occur, in this order: 75 | 1) The control's event will be invoked. If you need to perform one time setup operations on the CoreWebView2 prior to its use then you should do so in a handler for that event. 76 | 2) If a Uri has been set to the property then the control will start navigating to it in the background (i.e. these steps will continue without waiting for the navigation to finish). 77 | 3) The Task returned from will complete. 78 | 79 | For more details about any of the methods/properties/events involved in the initialization process, see its specific documentation. 80 | 81 | Accelerator key presses (e.g. Ctrl+P) that occur within the control will 82 | fire standard key press events such as OnKeyDown. You can suppress the 83 | control's default implementation of an accelerator key press (e.g. 84 | printing, in the case of Ctrl+P) by setting the Handled property of its 85 | EventArgs to true. Also note that the underlying browser process is 86 | blocked while these handlers execute, so: 87 | 88 | 89 | You should avoid doing a lot of work in these handlers. 90 | 91 | 92 | Some of the WebView2 and CoreWebView2 APIs may throw errors if 93 | invoked within these handlers due to being unable to communicate with 94 | the browser process. 95 | 96 | 97 | If you need to do a lot of work and/or invoke WebView2 APIs in response to 98 | accelerator keys then consider kicking off a background task or queuing 99 | the work for later execution on the UI thread. 100 | 101 | 102 | 103 | 104 | Cleans up any resources being used. 105 | 106 | true if managed resources should be disposed; otherwise, false. 107 | 108 | 109 | 110 | Overrides the base OnPaint event to have custom actions 111 | in designer mode 112 | 113 | The graphics devices which is the source 114 | 115 | 116 | 117 | Overrides the base WndProc events to handle specific window messages. 118 | 119 | The Message object containing the HWND window message and parameters 120 | 121 | 122 | 123 | Gets or sets a bag of options which are used during initialization of the control's . 124 | This property cannot be modified (an exception will be thrown) after initialization of the control's CoreWebView2 has started. 125 | 126 | Thrown if initialization of the control's CoreWebView2 has already started. 127 | 128 | 129 | 130 | Explicitly trigger initialization of the control's . 131 | 132 | 133 | A pre-created that should be used to create the . 134 | Creating your own environment gives you control over several options that affect how the is initialized. 135 | If you pass null (the default value) then a default environment will be created and used automatically. 136 | 137 | 138 | A Task that represents the background initialization process. 139 | When the task completes then the property will be available for use (i.e. non-null). 140 | Note that the control's event will be invoked before the task completes 141 | or on exceptions. 142 | 143 | 144 | Calling this method additional times will have no effect (any specified environment is ignored) and return the same Task as the first call. 145 | Calling this method after initialization has been implicitly triggered by setting the property will have no effect (any specified environment is ignored) and simply return a Task representing that initialization already in progress. 146 | 147 | Thrown when invoked from non-UI thread. 148 | Thrown when this instance of is already disposed. 149 | Thrown when browser process has unexpectedly and left this control in an invalid state.
