RebGUI enhancement request - active labels

 [1/7] from: btiffin:rogers at: 19-Mar-2007 12:58


Hi, The apps I've been writing use RebGUI 0.4.0. A major design philosophy I use is labelled fields. Clicking on the label pops up a requestor (usually using text-list filled from (sometimes large) databases) that fills in the field with selected choice. The use can click the label for a popup or enter data directly in the field. I needed the visual cue that the label is 'hot' so I modified label to this (perhaps inefficient, perhaps broken)... label: make text [ font: make default-font [style: 'bold] feel: make default-feel [ engage: func [face action event] [ switch action [ down [face/feel/over face false 0x0 face/action face] away [face/feel/over face false 0x0] ] ] over: func [face act pos] [ if (get in face 'action) [ either act [face/font/color: gold show face] [face/font/color: black show face] ] ] ] ] If there is an action block with the label, change to gold on a hover. This is a mod of old widget code from 0.4.0 Is it possible to get this feature built into the 'real' RebGUI? If a label has a click action, to highlight it some how? Thanks in advance, and I'm more than willing to hear a short response of "No". By the way, the last %tour.r I pulled out of svn doesn't segfault on Debian/GNU Linux - etch RC1 anymore. btiffin

Hi Brian, BT> If there is an action block with the label, change to gold on a hover. My only thought, not RebGUI related, is that UI elements should indicate they're clickable without the user having to mouse over them. Psychologists (and UI designers :) call these "affordances". e.g. clickable text could be underlined, like a link in a browser, but then also highlight on hover (since we can't change pointers in REBOL). --Gregg

I'd argue labels are the exception here. I think of underlined text as taking me somewhere, where a label is bound to a control element that merely changes its own, or the current page/form's state. Think what a page of Radio/Check Lines would look like underlined, or field labels that focus on their owner when clicked. Though perhaps you could consider the label text itself a visual indicator? However, in this specific case, it seems the label could be replaced by a button to indicate the altered behaviour -- I'd hate to click on a label expecting to operate the control, only for a requester to pop up... - Chris

Agreed. For requestors, I generally use a small button with an ellipsis as the caption, butted right up against the right side of the field. --Gregg

I agree with this. The couple of instances where I have used labels as buttons, I have now changed to buttons so that the interface is consistent. On 3/20/07, Gregg Irwin <gregg.irwin-gmail.com> wrote:

Hi Gregg, Yes you are right...but... I was going for a looky feely close to VID. view layout [label "Plain Label" label "Action Label" [print "action"]] Highlights Action Label when you mouseover. Thanks for the comments

I also agree with this. Anton.
