pull up r19860 from trunk r19860@cathode-dark-space: jaltman | 2007-08-24 10:38:45 -0400 ticket: new subject: NIM: Selection Issues component: windows Credentials selection in Network Identity Manager has usability issues due to the following causes: - The "cursor row" is not always selected. The "cursor row" is the row which the "cursor" is on. Navigating the credentials view using the keyboard or clicking the credentials display with the mouse will move the cursor to different rows. However, this cursor row is not always selected, especially when Network Identity Manager starts. Having the selection be independent of the cursor row is a requirement for supporting "toggle" selections (holding the 'ctrl' key while clicking), which is a standard way of doing multiple selections on Windows. The problem with the cursor row not being selected when Network Identity Manager starts is due to the delayed start of its plug-ins. Even though the first row is initially selected, when plug-ins complete initialization and notify the application about the credentials that they see, those credentials end up accumulating under different identities. The existing code didn't enforce the selection state of the identity on the newly added credentials. Since there were unselected credentials under the selected outline level, the code would then turn off the selected bit for the outline (which usually is an outline level for an identity) for consistency. The patch changes the behavior to enforce the selection state of the enclosing outline on any new outline levels or credentials that are added under it. This prevents an outline level from losing its selection state when new credentials are added under it. - Identities may have stale data associated with it. The credentials view maintains a set of cached properties for each identity that has credentials. During each refresh cycle, it would go through the credentials and update the properties of each identity. However it would not update the properties for identities that are not associated with any credentials. When the credentials associated an identity were deleted, the cached properties for that identity sometimes never got reset. If the identity was marked as "always visible", then it would be listed in the credentials view along with the stale properties. This patch properly initializes the properties of identities which are not associated with any identities. - Selection state is not updated when switching views. The credentials view maintains selection state for individual credentials when switching views. The same is not true for the outlines since the outline needs to be reconstructed during the switch. The exising code failed to update the selection state of the outlines after switching the view to reflect the the selection state of the credentials. As a result, once a the user switched a view, she might see outline levels which do not appear to be selected even though all the credentials contained at the outline level appear selected. This patch properly adjusts the selection state of outline nodes to correspond to the selection state of the contained credentials. - Selection state may be inconsistent when more than one credential is associated with a single row. Some rows may represent more than one credential. A collapsed outline represents all the credentials contained within that outline level. In addition, two credentials that will appear the same to the user (because all the displayed properties are the same) will be represented by one row. The selection state of these rows should be consistent with the selection state of all the credentials that it represents. The previous code did not enforce this constraint. This patch aims to fix this by enumerating all the credentials that are represented by each row and setting the selection state of each credential to match the selection state of the row.
