The STRANDS webserver package

Quite a lot information is missing here…

Modal Dialog

The webserver offers and actionlib server to display a modal dialog. Here is an example goal definition, the action interface is strands_webserver/modal_dlg:

title: 'This is a test'
text: 'We can use full HTML in here, e.g. <b>BOLD</b>'
buttons: ['OK', 'cancel']
buttons_class: ['btn-success']

buttons_class can be used to set Bootstrap button classes

The full action is defined as ModalDialogSrv.action:

# the title of the dialog (can be full HTML)
string title
# the main body of the dialog (HTML)
string text
# the HTML definition for the individual buttons (usually just a text)
string[] buttons
# option bootstrap button class, e.g. 'btn-default' or 'btn-success'
string[] buttons_class
---
# returns the HTML definition of the selected button
string button
# returns the index of the selected button
uint32 button_id
---
string feedback

The dialog is displayed as a bootstrap modal dialog, overlaying any information currently displayed. Preempting the actionlib goal will hide the dialog, otherwise it is dismissed as soon as the user clicks on of the defined buttons and the actions returns success in this case. The action server returns “feedback” once the dialog has been rendered on the user’s screen. The feedback is the full generated HTML definition of the dialog displayed (not very useful, but hey, at least you know when it is displayed).
