## Full Menu View
|
||||
A full menu view supports displaying a list of times on a screen in a very configurable manner. A full menu view supports either a single row or column of values, similar to Horizontal Menu (HM) and Vertical Menu (VM), or in multiple columns.
|
||||
|
||||
## General Information
|
||||
|
||||
Items can be selected on a menu via the cursor keys, Page Up, Page Down, Home, and End, or by selecting them via a `hotKey` - see ***Hot Keys*** below.
|
||||
|
||||
:information_source: A full menu view is defined with a percent (%) and the characters FM, followed by the view number. For example: `%FM1`
|
||||
|
||||
:information_source: See [Art](../art.md) for general information on how to use views and common configuration properties available for them.
|
||||
|
||||
### Properties
|
||||
|
||||
| Property | Description |
|
||||
|-------------|--------------|
|
||||
| `textStyle` | Sets the standard (non-focus) text style. See **Text Styles** in [Art](../art.md) |
|
||||
| `focusTextStyle` | Sets focus text style. See **Text Styles** in [Art](../art.md)|
|
||||
| `itemSpacing` | Used to separate items vertically in the menu |
|
||||
| `itemHorizSpacing` | Used to separate items horizontally in the menu |
|
||||
| `height` | Sets the height of views to display multiple items vertically (default 1) |
|
||||
| `width` | Sets the width of a view to display one or more columns horizontally (default 15)|
|
||||
| `focus` | If set to `true`, establishes initial focus |
|
||||
| `submit` | If set to `true` any `accept` action upon this view will submit the encompassing **form** |
|
||||
| `hotKeys` | Sets hot keys to activate specific items. See **Hot Keys** below |
|
||||
| `hotKeySubmit` | Set to submit a form on hotkey selection |
|
||||
| `argName` | Sets the argument name for this selection in the form |
|
||||
| `justify` | Sets the justification of each item in the list. Options: left (default), right, center |
|
||||
| `itemFormat` | Sets the format for a list entry. See **Entry Formatting** in [Art](../art.md) |
|
||||
| `fillChar` | Specifies a character to fill extra space in the menu with. Defaults to an empty space |
|
||||
| `textOverflow` | If a single column cannot be displayed due to `width`, set overflow characters. See **Text Overflow** below |
|
||||
| `items` | List of items to show in the menu. See **Items** below.
|
||||
| `focusItemFormat` | Sets the format for a focused list entry. See **Entry Formatting** in [Art](../art.md) |
|
||||
|
||||
|
||||
### Hot Keys
|
||||
|
||||
A set of `hotKeys` are used to allow the user to press a character on the keyboard to select that item, and optionally submit the form.
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
hotKeys: { A: 0, B: 1, C: 2, D: 3 }
|
||||
hotKeySubmit: true
|
||||
```
|
||||
This would select and submit the first item if `A` is typed, second if `B`, etc.
|
||||
|
||||
### Items
|
||||
|
||||
A full menu, similar to other menus, take a list of items to display in the menu. For example:
|
||||
|
||||
|
||||
```
|
||||
items: [
|
||||
{
|
||||
text: First Item
|
||||
data: first
|
||||
}
|
||||
{
|
||||
text: Second Item
|
||||
data: second
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### Text Overflow
|
||||
|
||||
The `textOverflow` option is used to specify what happens when a text string is too long to fit in the `width` defined. Note, because columns are automatically calculated, this can only occur when the text is too long to fit the `width` using a single column.
|
||||
|
||||
:information_source: If `textOverflow` is not specified at all, a menu can become wider than the `width` if needed to display a single column.
|
||||
|
||||
:information_source: Setting `textOverflow` to an empty string `textOverflow: ""` will cause the item to be truncated if necessary without any characters displayed
|
||||
|
||||
:information_source: Otherwise, setting `textOverflow` to one or more characters will truncate the value if necessary and display those characters at the end. i.e. `textOverflow: ...`
|
||||
|
||||
