Composable context menus
A method includes automatically generating application code to implement a context menu in an application, the application code comprising code for providing a context menu container object as part of an application page when the application page is displayed by a browser, the context menu container object configured not to be visibly displayed as part of the application page, the context menu container object configured to hold a current set of context menu options during display of the application page, consume a first event during display of the application page, and evaluate logic based on the first event to update the current set of context menu options during display of the application page, the context menu container object responsive to a prescribed input to display the context menu as having the current set of context menu options.
1. A computer program product comprising a non-transitory computer readable medium storing therein a set of computer executable instructions, the set of computer executable instructions comprising instructions for:
receiving a context menu definition for a context menu, the context menu definition comprising a context menu option definition, the context menu option definition comprising logic to be evaluated at runtime to determine context menu options to display; and
including application code to implement the context menu in an application, based at least in part on the context menu option definition, the application code comprising code for providing a context menu container object as part of an application page when the application page is displayed by a browser, the context menu container object configured not to be visibly displayed as part of the application page, the context menu container object configured to hold a current set of context menu options during display of the application page, consume a first event during display of the application page, and evaluate the logic based on the first event to update the current set of context menu options during display of the application page, the context menu container object responsive to a prescribed input to display the context menu as having the current set of context menu options.
2. The computer program product of claim 1 , wherein the application code comprises code for initializing the context menu container object with a default set of menu options as the current set of context menu options.
3. The computer program product of claim 1 , wherein the context menu definition includes an action definition specifying an action associated with a first context menu option and wherein the context menu container object is configured to perform the action based on a user selection of the first context menu option in the context menu.
4. The computer program product of claim 1 , wherein the context menu definition includes an action definition, the action definition comprising an expression to be evaluated at runtime to determine an action to perform upon selection of a first context menu option and wherein the context menu container object is configured to evaluate the expression to determine the action and bind the action to the first context menu option.
5. The computer program product of claim 4 , wherein the expression includes a payload of the first event as an argument.
6. The computer program product of claim 4 , wherein the expression includes an application context data as an argument.
7. The computer program product of claim 4 , wherein the expression includes a value from a data source as an argument.
8. The computer program product of claim 4 , wherein the action comprises publishing an application user interface.
9. The computer program product of claim 4 , wherein the action comprises publishing a second event to an event bus.
10. The computer program product of claim 1 , wherein the application code further comprises code for:
providing a set of action elements associated with the context menu;
receiving a selection of a first context menu option while the context menu is displayed;
performing chained actions while the context menu is displayed; and
maintaining a binding to action elements in the set of action elements to continue processing of the chained actions after the context menu is no longer displayed.
11. A method comprising:
receiving a context menu definition for a context menu, the context menu definition comprising a context menu option definition, the context menu option definition comprising logic to be evaluated at runtime to determine context menu options to display; and
based at least in part on the context menu option definition, automatically generating application code to implement the context menu in an application, the application code comprising code for providing a context menu container object as part of an application page when the application page is displayed by a browser, the context menu container object configured not to be visibly displayed as part of the application page, the context menu container object configured to hold a current set of context menu options during display of the application page, consume a first event during display of the application page, and evaluate the logic based on the first event to update the current set of context menu options during display of the application page, the context menu container object responsive to a prescribed input to display the context menu as having the current set of context menu options.
12. The method of claim 11 , wherein the application code comprises code for initializing the context menu container object with a default set of menu options as the current set of context menu options.
13. The method of claim 11 , wherein the context menu definition includes an action definition specifying an action associated with a first context menu option and wherein the context menu container object is configured to perform the action based on a user selection of the first context menu option in the context menu.
14. The method of claim 11 , wherein the context menu definition includes an action definition, the action definition comprising an expression to be evaluated at runtime to determine an action to perform upon selection of a first context menu option and wherein the context menu container object is configured to evaluate the expression to determine the action and bind the action to the first context menu option.
15. The method of claim 14 , wherein the expression includes a payload of the first event as an argument.
16. The method of claim 14 , wherein the expression includes an application context data as an argument.
17. The method of claim 14 , wherein the expression includes a value from a data source as an argument.
18. The method of claim 14 , wherein the action comprises publishing an application user interface.
19. The method of claim 14 , wherein the action comprises publishing a second event to an event bus.
20. The method of claim 11 , wherein the application code further comprises code for:
providing a set of action elements associated with the context menu;
receiving a selection of a first context menu option while the context menu is displayed;
performing chained actions while the context menu is displayed; and
maintaining a binding to action elements in the set of action elements to continue processing of the chained actions after the context menu is no longer displayed.
