+++ This bug was initially created as a clone of Bug #245366 +++ Created an attachment (id=111048) Cannot scroll via KB in preference Build ID: I20080617-2000 Steps To Reproduce: 1. Set up the High Contrast mode for Windows OS, by selecting the High Contrast settings in Control Panel -> Accessibility Options -> Display 2. Launch Eclipse, and open the preference dialog 3. Navigate to General -> Appearance. You will find that, the right side content can not be displayed in one page, and a vertical scrollbar is shown up automatically. However, using keyboard only, you can not perform scrolling, thus you can not view the content hided in the bottom. 4. Navigate to Run/Debug -> Launching page, you will find that both veritical and horizontal scroll bar are shown up. But, with keyboard only, you can not perform any scrolling actions.

Consider a non-API work around for 3.4.2 PW
Kim and I should have a conversation with Duong. PW
Created attachment 118919 [details] Cheap implementation for 3.4.2 ... SWT example with key filter This is a potential solution for 3.4.2 (based on one of the SWT snippets). Basically a key filter that honours a few SWT keys to "manually" move the ScrolledComposite, and becomes disabled on the first key event that doesn't look like ours. PW
Created attachment 118936 [details] Filtered Preference Dialog v01 This is (potentially) the basic structure of key assisted scrolled composite. Carolyn, what kind of events should we be watching here? Should they only be traverse events and not keydown events? Kim, why is nothing in the PreferencesDialog done in a dispose listener, only in close. Is it fine when ESC is called and the dialog disappears? PW

This patch looks good to me.

Requesting status.
Sorry.. I didn't see your comment #6 was today! Just wanted to see if we were going to get it in 3.4.2. Looks like it probably will.. thx

Looks like it probably will.. thx > A little more investigation on my part and it should be a workaround for 3.4.2. It should be in by next week's maintenance build. Basically we're adding a second menu item to the preferences dropdown menu (accessible with CTRL+F10) that will allow movement in response to the 4 arrow keys + page up/page down. PW
Created attachment 119805 [details] Pref Dialog v02 This is a more refined patch. It responds to up, down, left, right, page up, page down, home, and end. It eats the key or traverse event when it deals with it. Any key event that isn't dealt with puts us out of scrolling mode. PW
Created attachment 120199 [details] Pref Dialog v03 Same as v02 except adds a display==null and an isDisposed() check in the filter PW
