Polymorph - TabIndex and layoutFrames questions
 
|
1- How i can change the #position or #extent of a Morph with a layoutFrame setted ? for example, i have a button "anchored" to top and right; if i set the #position: of that button the position don´t change. Then i try override the #position: accessor of my button; first set #layoutframe: to nil, later do the set normally of #position: and later set again the old value of #layoutFrame: , for remain the original anchors. But don´t works. Well, if I execute the code in a WorkSpace, line to line, then works! but don´t if execute all code. I don´t understand :| 2- How works the tab index mechanism in Polymorph? in some of my Views i have controls with unordered tab order in controls. How i can change the order? I don´t see nothing for start. 3- Exists the possibility of change the position of cursor of a textbox? Regards, and thanks for the help |

BTW I was thinking about your work (I still have to play with it).
IN MC UI they build the UI useing spec look at buildWindow buildWindow | window | window := SystemWindow labelled: self label. window model: self. self widgetSpecs do: [:spec | | send fractions offsets | send := spec first. fractions := spec at: 2 ifAbsent: [#(0 0 1 1)]. offsets := spec at: 3 ifAbsent: [#(0 0 0 0)]. window addMorph: (self perform: send first withArguments: send allButFirst) fullFrame: (LayoutFrame fractions: ((fractions first)@(fractions second) corner: (fractions third)@(fractions fourth)) offsets: ((offsets first)@(offsets second) corner: (offsets third)@(offsets fourth)))]. ^ window buttonSpecs ^ #((Invert invert 'Show the reverse set of changes') (Export export 'Export the changes as a change set')) widgetSpecs ^ { #((listMorph:selection:menu:keystroke: list selection methodListMenu: methodListKey:from:) (0 0 1 0.4) (0 0 0 0)). { #(textMorph: annotations). #(0 0.4 1 0.4). { 0. 0. 0. self defaultAnnotationPaneHeight. } }. { #(textMorph: text). #(0 0.4 1 1). { 0. self defaultAnnotationPaneHeight. 0. 0. } }. } this is minimal and not optimal but this is nice to have an array of literal to describe a UI Stef On Sep 13, 2009, at 10:48 PM, nullPointer wrote: > > > 1- How i can change the #position or #extent of a Morph with a > layoutFrame > setted ? > > for example, i have a button "anchored" to top and right; if i set the > #position: of that button the position don´t change.

I don´t know how do that. Seems very complicated for me.
I did think in each widgets implements a method where return his state. The code will be more readable ( i believe ) and seems more easy of implement ( i believe too ) regards 2009/9/14 Stéphane Ducasse-2 (via Nabble) <[hidden email]> BTW I was thinking about your work (I still have to play with it). |

1. position/extent depends on how thae morph is laid out in its owner.
LayoutFrame is used when the owner specified a proportional layout, use the fractions to pin corners and the offsets to.. offset. If the owner specifies no layout then postion/extent work as expected. For table layouts things are more complicated (see hResizing/vResizing etc.) 2. Tab order (keyboard navigation) follows the order of the submorphs at present. Add your morphs (using addMorphback: or via the Polymorph row/column type stuff) in the order you want navigation to follow.

1. I have always work with owners in ProportionalLayout, don´t let work with another layoutPolicy in the canvas designer. In view designer exists the possibility of "anchor" a widget to top, left, down and right. That is all need the user ( for the moment ) for anchor a widget, but fails to change size and position.Exists the possibility of do it in ProportionalLayout on owner?
2. Then i understand than changing the order of submorphs that works? I will probe. Regards and many thanks. 2009/9/14 Gary Chambers (via Nabble) <[hidden email]> 1. position/extent depends on how thae morph is laid out in its owner. |

1. "Fixed" positioning can be achived by setting
the fractions to [hidden email] for top-left and bottom-right then
using the offsets.

1.
Here's the (I believe) equivalent LayoutFrames settings: #anchorRight - rightFraction: 1 rightOffset: -pixelsToRight #anchorBottom - bottomFraction: 1 bottomOffset: -pixelsToBottom #anchorLeft - leftFraction: 0 leftOfffset: pixelsToLeft #anchorTop - topFraction: 0 topOffset: pixelsToTop The problem with having just those four options is they don't work well with resizing when you have more than one widget (try placing two side by side and locking left + right)... In those cases you usually want a fraction somewhere between 0/1 for at least one of the edges, and adjust those a couple of pixels to make a constant size border between morphs, like this: Morph1 - leftFraction: 0 leftOffset: 5 rightFraction: 0.5 rightOffset: -2 Morph2 - leftFraction: 0.5 leftOffset: 2 rightFraction: 1 rightOffset: -5 2. Yes, I believe so. Note, this might also modifiy their rendering order (I haven't checked though), which could be important if you have partially overlapping morphs Cheers, Henry nullPointer skrev: > 1.

In reply to this post by Gary Chambers-4
i´m already using fractions and offsets, through my class CLDecorMorph... http://paste.lisp.org/display/87049 (Note: in that class properties as #position or #top, #left etc be relatives to owner) I´m use the owner always with ProportionalLayout and the "anchors" with the fractions-offsets mechanism. The problem is when I try set the #position: or #extent: accessors. Don´t works.

Alternatively you could use or: or: or: / | | |, drop the not's, and switch the ifTrue:ifFalse: blocks. That way, the "interesting" case comes on top too :). Personally, I'd also use ifNotNil:, and temps moved to their enclosing scope in this method, but as you say, preferences differ. :) Cheers, Henry _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

#position: and #extent: etc. won't work since the owner is laying out as per

It is not a problem, as such. Just the wau layouts work.
