[chromium-dev] Re: Tab Thumbnails and Aero Peek (of Windows 7)
Hi Brett, Thank you for your suggestions. I would like to use the default size and resize it in my code that creates tab thumbnails. Regards, Hironori Bono E-mail: hb...@chrommium.org 2009/10/24 Brett Wilson bre...@chromium.org: 2009/10/23 Hironori Bono (坊野 博典) hb...@google.com: Hi Brett, Thank you so much for noticing this. I'm integrating the ThumbnailGenertor class into my prototype now. :) By the way, I'm a little wondering if there is a function that changes the width and the height of a thumbnail image generated by the ThumbnailGenerator class at run time. If not, I would like to hear there is a plan to add it. When Windows 7 shows tab thumbnails, it automatically calculates the width and the height of a thumbnail image so that it can show all thumbnails in one line. (When we open too many tabs and Windows 7 cannot show their thumbnails, it shows a list of tab titles.) In brief, we cannot assume the width or the height of a thumbnail as constant values on Windows 7. So, it may be better for the ThumbnailGenerator class to have an interface that changes the width and the height of its thumbnails. (I has added code that resizes the thumbnails retrieved from the ThumbnailGenerator object and sends the resized thumbnails to Windows 7. So, I don't mind it at all.) There isn't a way to do this. The reason is that the thumbnail generator precalculates thumbnails in advance for many pages (for example, when we're discarding the backing store). This means we have to know basically when we start Chrome what the max thumbnail size will be. It uses power-of-two downsampling to be as fast as possible, so the actual thumbnails aren't guaranteed to be any particular size. I would just use the default size for now. If it doesn't look OK, we can add a future enhancement to request the size, so the ones it generates on-demand (the ones where there is a backing store) can have a larger size if needed.

Hi Mike, Thank you for your question and suggestion. On Sat, Oct 24, 2009 at 2:19 AM, Mike Pinkerton pinker...@chromium.org wrote: All the screenshots show this with a single window. What happens if you have multiple windows open? Does it only show the selected window? Unfortunately, the current prototype just shows the thumbnails of the all Chromium windows. I realize many users like to see only the thumbnails of the selected window and would like to implement it. Nevertheless, to show only the thumbnails of the selected window, we probably need to handle more events than the ones handled by the current prototype (such as detaching a tab, attaching a tab, creating a popup window, creating a dialog, etc.) and choose the window to which a tab (a pop-up window, or a dialog) belongs. Unfortunately, my current prototype is still an infant phase and it is not good time to implement such complicated logics. As an alternate suggestion, we have a mode in Camino2 called tabspose which is like OS X Expose, but shows the (large) thumbnails of all open tabs overlaying the content area of the browser. Allows much better visualization of the tabs because you're not limited to small squares but can use as much of the window as available. This does involve interacting with the window already, so it doesn't work until you have the window in the foreground, but I wanted to bring it up as an idea. http://www.flickr.com/photos/spaunsglo/987375693/ for an early screenshot (currently looks more polished, but same idea). Thank you for your link. I'm going to look into it. :) Regards, Hironori Bono E-mail: hb...@chromium.org 2009/10/23 Brett Wilson bre...@chromium.org: 2009/10/23 Hironori Bono (坊野 博典) hb...@google.com: Hi Brett, Thank you so much for noticing this.

[chromium-dev] Re: Tab Thumbnails and Aero Peek (of Windows 7)
Hi Hironori, Thanks for researching this topic. On generating thumbnails, I wrote chrome/browser/tab_contents/thumbnail_generator which tries to get the most up-to-date thumbnail images for all tabs (except ones that haven't ever been shown) with minimal performance overhead. The code hasn't been used much in practice yet, but seems to basically work. It was written for a tab switcher, and the intent is that it will provide thumbnails for all services in the future (including the new tab page and the Windows 7 features) for all platforms. So I would definitely use that, and we should work on fixing any bugs or limitations that pop up. It's defaulted to off for most builds because it has a runtime overhead and its not currently used. If you want to turn it on for your build, it's started in the constructor for TabContents.

2009/10/22 Hironori Bono (坊野 博典) hb...@chromium.org How to treat resize events of a browser window? The biggest problems of my current prototype are caused by my prototype that doesn’t handle resize events of a browser window. (Figure 4 may be acceptable. But, I think Figure 5 is unacceptable for many users.) The easiest solution for this problem is forcing a background tab to redraw when we need an image used for Aero Peek or Tab Thumbnails. Unfortunately, this solution probably hurts the rendering performance of Chromium. Another solution (or a workaround) is displaying a message “the preview image for the selected tab is not available” instead of showing a broken image. Any opinions or suggestions are definitely helpful. Firefox nightlies now supports tab preview. If you resize the window the background tabs keep their old thumbnails which I think is acceptable. -- erik --~--~-~--~~~---~--~~ Chromium Developers mailing list: chromium-dev@googlegroups.com View archives, change email options, or unsubscribe: http://groups.google.com/group/chromium-dev -~--~~~~--~~--~--~---
