Bug 799363 - When selecting "load" two layer ... #2094
Conversation
The Back and Forward buttons now work correctly. Added pressedBACK and pressedFWD to _gnc_html_history because gnc_html_history_append needs to know if a button has been pressed. I had to remove the Back and Forward options from the right-click menu because they interfere with the buttons' functionality. Clicking and selecting Load clears the existing Forward order. I can't change it because it's JavaScript inside the HTML.

Don't duplicate code. You could extract this to a separate function that takes the WebKitContextMenuAction as an argument and call it twice.
But you don't need to do either. You can keep on working with the list, you just need to advance the node before you delete it:
for (GList* node = menu_items; node;)
{
WebKitContextMenuItem *item = WEBKIT_CONTEXT_MENU_ITEM (node->data);
WebKitContextMenuAction action = webkit_context_menu_item_get_stock_action (item);
node = g_list_next (node);
if (action == WEBKIT_CONTEXT_MENU_ACTION_GO_BACK ||
action == WEBKIT_CONTEXT_MENU_ACTION_GO_FORWARD)
webkit_context_menu_remove(context_menu, item);
}

Avoid single-letter names except for integer indexes. node is a typical name for list members.
Always put curly braces on their own line. GnuCash's style specifies that they should be flush with the introducing line.

That makes the context menu different from those of most browsers. Better to replace the menu items with new ones that use the same actions as the toolbar buttons.

I managed to create "Back" and "Forward" items in the context menu, but I don't know how to call gnc-plugin-page-report.c::gnc_plugin_page_report_back_cb from a function in gnc-html-webkit2.c with report as a parameter. Is possible? |
Yes, via the navigation policy in |

@jralls Could you please give me an example?, because I don't find any examples on code nor documentation about |
