Adding context menus to fields [message #1064444]

In our application we have a requirement that we need to be able to execute some actions from fields based on their content. As an example there might be a StringField containing someone's e-mail address, we would then need to offer the possibility of letting the user send a message to that e-mail address. Or we might have an icon indicating some status and would like to be able to change this status by interacting with the image. The easiest thing to make this possible from a user perspective would be using a context menu on those elements.

In the Scout SDK I didn't see a possibility of adding menu entries to anything but a table field. Is it possible to add a context menu to another field (say an ImageField or anything derived from ValueField)? If so, how would I do this?

From what I know, for the moment menus can be added to:
* Table
* Button
* SmartField

I think that the application model could be extended...

Is this something I could do myself or does it involve heavy digging in the scout internals?

I is probably no "heavy digging", but I do not see how you can change it, without changing stuff in the Scout classes:
- Application model: you will need a "IMenu[] getMenus()" method on the interfaces representing the corresponding fields -- similar to what you have on ISmartField
- Rendering engine (eg org.eclipse.scout.rt.ui.swt) needs to render these menus.

Thanks for your reply, in that case I'll open a Bug for this.

Adding context menus to all value fields has been requested before. But, because context menus are not very practical on a mobile platform, it was not implemented.

You can however define context menus on image fields: You can find an example here on LeftField: https://github.com/BSI-Business-Systems-Integration-AG/org.eclipsescout.demo/blob/master/widgets/org.eclipsescout.demo.widgets.client/src/org/eclipsescout/demo/widgets/client/ui/forms/ImageFieldForm.java

Thanks for your reply. Context menus might not be very practical on a mobile platform, but it seems like a shame that a feature that would be very practical in an SWT client is not available just because it isn't a benefit to mobile platforms.

Edit: removed comments about not finding anything in LeftField about how to add context menus to ImageFields as I just found out that ImageFields already support context menus in the SDK, don't know how I missed that...

I've now successfully added a context menu to an ImageField and can access it by right-clicking the image.

However, on of our requirements is that the application be usable only with the keyboard (without the mouse).

However, even though my ImageField has both the "Focusable" as well as the "Focus visible" property set, I do not seem to be able to focus it (either using the Tab key or using the mouse to left click on it). As the image is not focusable, I cannot use the "context menu key" on the keyboard to open the context menu (something that works on a table for example). I thought I'd add a keystroke to do that, but here I have the same problem, as I cannot set the focus on the ImageField, any keystrokes I define for it does not seem to be triggered.

As a workaround, I've defined a keystroke on the containing GroupBox which *is* triggered. How would I trigger the display of the the ImageField's context menu from the keystroke's execAction command?

I created Bug 429556 for the issue that the imagefield cannot get the focus.
