Starting in v2017.1, administrators can provide custom ExpressView themes for their users. Themes are made by using the ExpressView Designer, by editing and supplying custom JSON files from a template, or by using the Exago Theme Maker.

Note

This section applies to ExpressView in pre-v2021.1 of the application. For v2021.1+ see ExpressView (v2021.1+)

The ExpressView Designer allows you to preview themes as you are making them, but it is more limited than editing the files. You may want to get started with the designer, then make any additional changes directly in the theme files.

Using the ExpressView Designer

The ExpressView Designer lets you make themes in the same manner as you would style individual ExpressViews. When you select an element to style, the designer will highlight in blue all the sections that will receive the styling. Styling changes are made in the Style section of the right pane or by right-clicking a specific section of the report to be edited.

Right-click styling:

Applicable elements are:

• Each level of Group Header
• Alternating Group Colors (the Radial Menu icon)
• Each subsequent Column Header (or "Detail Header")
• Each subsequent Detail Section
• Each level of each subsequent Group Footer
• Each subsequent Report Footer
• Alternating Detail Row colors

As of v2018.2, you can use select multiple elements to style at once by holding the Ctrl key and clicking the elements you would like to edit. For example, you can select the detail section of every column and change the font type in one stroke so that each column doesn't have to be styled individually. Similarly, you can also select and edit all of the headers at one time.

You can also Ctrl select across different sections so that different levels of headers and the detail section can be edited at one time. 

Note

Styling edits ranging across multiple sections must be done in the right pane.

To make an ExpressView theme using the designer:

1. Create or open an ExpressView for editing.
2. Add enough data fields and groupings to have all the elements you want to style.
3. Style the ExpressView as normal. See ExpressView: Customizing Appearance.
4. When finished, while holding Ctrl + Alt + Shift, click the Save  icon.
5. Enter a name and optionally, a report path to save the theme.
6. Click OK.

Manually Editing Theme JSON Files

You can build ExpressView themes manually by writing JSON to text files with a .wrtev file extension. Instead of building them from scratch, you may want to make themes using the Designer first, then edit the files to add what you want. Or locate the Legacy.wrtev theme, which is blank, then make a copy and use that as a template.

Editing theme files gives you some more options, namely the ability to set border colors and widths for the different elements.

First you will have to familiarize yourself with the JSON format. See Using JSON to get started.

ExpressView Theme JSON

The theme JSON is an object with the following properties:

Example

{
  "FormatTheme":         "Example",
  "GroupHeaderFormats":  [ {format}, {format} ],
  "GroupFooterFormats": [[ {format}, {format}, {format} ], 
                         [ {format}, {format}, {format} ]],
  "ColumnHeaderFormats": [ {format}, {format}, {format} ],
  "DetailFormats":       [ {format}, {format}, {format} ],
  "ReportFooterFormats": [ {format}, {format}, {format} ],
  "RowShading":          [ "color", "color" ],
  "GroupColors":         [ "color", "color", "color" ]
}

Format objects define the styling for a particular element. They are described below.

  "FontColor": "#FFFFFF",
  "BackgroundColor": "#4C5D60",
  "Weight": 3,
  "Underline": 0,
  "HorizontalAlign": 0,
  "VerticalAlign": 1,
  "WrapText": true,
  "UniformBorder": false,
  "BorderFormatting": {
    "TopColor": "#ededed",
    "TopWeight": 1,
    "LeftColor": "#ededed",
    "LeftWeight": 0,
    "BottomColor": "#ededed",
    "BottomWeight": 1,
    "RightColor": "#ededed",
    "RightWeight": 0
  }
}

Setting a Default Theme

If you want to make a theme the default for all new ExpressViews in the environment, change the config file setting <expressviewdefaultformattheme> to the name of the theme.
