The modal message is usually generated with the ButtonWidget. The modal message is handled by the TiddlyWiki core.

Fields within the tiddler being displayed in the modal can be used to customise its appearance.

paramObject

The "currentTiddler" variable is set to the title of the modal tiddler, but can be overridden by specifying a different value in paramObject.

Example

Here is an example of displaying a modal and passing parameters to it: (Note how all parameters to action-sendmessage other than $param and $message are available as variables within the modal.)

Your name: <$edit-text tiddler="$:/temp/yourName" tag="input" default="Your name"/>

Your message:
<$edit-text tiddler="$:/temp/yourMessage" default="Your message"/>

<$button>
<$action-sendmessage $message="tm-modal" $param="SampleModal" yourName={{$:/temp/yourName}} yourMessage={{$:/temp/yourMessage}}/>
Click me!
</$button>
