title: WidgetMessage: tm-open-window
type: text/vnd.tiddlywiki

The `tm-open-window` [[message|Messages]] opens a tiddler in a new //browser// window. If no parameters are specified, the current tiddler is opened in a new window. Similiar to `tm-modal` any additional parameters passed via the <<.param "paramObject">> are provided as variables to the new window.

|!Name |!Description |
|param //{default param}//  |Title of the tiddler to be opened in a new browser window, defaults to <<.var "currentTiddler">> if empty |
|template |Template in which the tiddler will be rendered |
|windowTitle |Title string for the opened window |
|width |Width of the new browser window |
|height |Height of the new browser window |
|left|<<.from-version "5.2.2">> Optional, left position of new browser window|
|top|<<.from-version "5.2.2">> Optional, top position of new browser window|
|windowID|<<.from-version "5.2.2">> Optional, unique string used to identify the widow. Can be used with [[WidgetMessage: tm-close-window]] to close the window. Defaults to the value of <<.param param>> |
|//{any other params}// |Any other parameters are made available as variables within the new window |

The `tm-open-window` message is best generated with the ActionSendMessageWidget, which in turn is triggered by a widget such as the ButtonWidget. The message is handled by the core itself.

<<.tip """When used with the ActionSendMessageWidget, <<.param 'param'>> becomes <<.param '$param'>> """>>
<<.tip """Parameters <<.param template>>, <<.param windowTitle>>, <<.param width>>, <<.param height>>, <<.param left>> and <<.param top>> require the ActionSendMessageWidget.""">>
<<.tip """<<.from-version 5.2.2>> To close a window opened with tm-open-window use [[WidgetMessage: tm-close-window]]""">>
<<.tip """<<.from-version 5.2.2>> To open a tiddler in more than one new window, use a unique value for <<.param windowID>>""">>
