Customizing action behavior and appearance

ManiVault’s actions offer numerous customization options, enabling both plugin developers and application designers to tailor the behavior and appearance of these GUI blocks.

Customization by Plugin Developers (Design-Time)

When coding a plugin, developers can configure each action’s properties and options to suit the plugin’s needs. Some examples:

• Default Values & Ranges
  When instantiating an action, you can provide default values. For numeric actions, you can also set ranges (min/max) and step sizes. This defines the allowed input domain and initial state of the control.

• Widget Configuration
  Many actions support flags or parameters to adjust their visual component. For instance, a DecimalAction can be configured to show a slider, a spinbox, or both. If a parameter makes sense as a slider (e.g. 0 to 100), the developer can enable the slider control; if fine-grained numeric input is needed, they might show just a spinbox. In fact, ManiVault’s decimal action lets you specify which sub-widgets to include, and will create them on-the-fly and keep them in sync (typing in the box moves the slider, and vice-versa). Similarly, StringAction can be either a single-line text field or a multi-line text area depending on a flag – you might choose a multi-line TextEdit for long text input versus a LineEdit for short text.
