Re: [squeak-dev] SystemWindow drag to edges in Inbox
by Jakob Reschke 15 Jan '16

15 Jan '16

In Windows, I tend to like both maximizing a window when it is dragged to the top of the screen and tiling a window when dragged to the left or right edge of the screen. Not sure why I find the first one more intuitive than double clicking the title bar or the window decoration button for it. Maybe it's that gross motion thing Chris mentioned. Just today, I came to dislike once again that the tiling does not work on the inner edges in a dual screen setup. Though, it is possible that I would change my mind if it worked and it would trigger all the time. Anyway, it is achievable with Win-key+Left/Right. On the other hand, I am not so keen on maximizing a window in only one direction (vertically or horizontally) if I drag an edge of the window to the edge of the screen. Windows has that for the vertical direction. But I cannot remember the last time I wanted to maximize a SystemWindow in Squeak... usually I find screen space to be more precious (scarce?) here because there is no web browser or dedicated text editor window, but rather a plethora of smaller windows floating around, each of them preferably only one click away. And I like to spare a hole somewhere to access the world menu... Maybe these habits are also a result of the lack of an Alt+Tab or Exposé like feature by default. 2016-01-11 22:01 GMT+01:00 Nicolas Cellier <nicolas.cellier.aka.nice(a)gmail.com>: > I wanted to comment that there's even more upsetting: the maximize feature > of windows 7 when dragging a window near display edge. > But as long as we can disable the preference, it's ok for me. > > 2016-01-11 20:20 GMT+01:00 Chris Muller <asqueaker(a)gmail.com>: >> >> Bernhard, please don't take this as offense but just as someone who's >> interested in UI design -- I'm curious what people find to like about >> this feature.

How to change balloon help colors?
by Chris Muller 15 Jan '16

15 Jan '16

I want to have BalloonMorphs with translucent color and white text. Setting BalloonMorph class>>#setBalloonColor: with a TranslucentColor does not work -- it sets the color but displays only at alpha 1.0. Adding the following to (BalloonMorph class>>#getTextMorph:for:) as the last line before the return: m textColor: Color white does not work.
