Tool Dialog Prompts

Dialog prompts are an essential part of Tool Integration Development and Services in EiffelStudio. As such we have provide a number of EiffelStudio specific classes for creating and displaying EiffelStudio dialog prompts.

Consistent Look and Feel

As of EiffelStudio 6.1, EiffelStudio uses custom dialog prompts that come in a flavor of presentation that stands above the stock dialog prompts found in EiffelVision2. As such all dialog prompts in EiffelStudio should be using the new prompt classes instead of those found in EiffelVision2 or the slightly specialized versions found in previous versions of EiffelStudio.

Just to get an idea of what the new prompts look like, here’s an example:

New prompts in EiffelStudio

For more examples of the new dialog prompts in EiffelStudio 6.1 see Taxonomy of Dialog Prompts.

New Features

The new dialog prompts in EiffelStudio no only have an update look and feel to them but the come with a number of added benefits for both end-users and EiffelStudio tool developers:

  • Brand new look.
  • Automatic layout of widgets and other text.
  • Button layouts are platform-dependent (Ok|Cancel on Windows, Cancel|Ok on Mac OSX.)
  • Dual-model; providing agent actions to perform on button presses and/or retrieval of the dialog result code.
  • Simplified interfaces with less code to write.
  • Extendable (see ES_DISCARDABLE_COMPILE_SAVE_PROMPT.)
  • Provides both standard and advanced creation routines for quick or complex creation.
  • An abstraction that makes it easy to replace the prompts in the future, updating the look etc.
  • Dialog prompts are always modal to the parent window.
  • Automatic location of the last active EiffelStudio window so tools need not worry about window management.
  • Automatic key navigation binding; Use of TAB, LEFT or RIGHT cursor keys and button first(or next)-character key (Yes => Y, Create => C, ...)
  • Ability to set a default active button.

Choosing a Dialog Prompt

Making the correct choice as to which dialog prompt to display is crucial, and is not as easy as you think. There is a page dedicate to deciding what dialog prompt is best suited for the need of a particular message - Taxonomy of Dialog Prompts. For help on choosing and formatting dialog prompt messages, see Dialog Prompt Messages and Formatting.

Displaying Dialog Prompts, the Easy Way

For the simplest way to show dialog prompts inside EiffelStudio or to use dialog prompts in the Eiffel framework library see Using Dialog Prompts (Basic).

Displaying Dialog Prompts, the Other Way

For more control over the way dialog prompts are display and how users interact with them, see Using Dialog Prompts (Advanced).

Displaying Discardable Dialog Prompts

The final set of dialog prompts are discardable dialog prompt. Discardable dialog prompts allows the user to opt out of seeing the dialog prompt subsequent showings. For information on using discardable dialog prompts, see Using Dialog Prompts (Advanced Discardable).
