Volkert, I tried in 2 #40621 images of mine and it worked fine. Both Zn included and Zn #bleedingEdge. Maybe it was some temporary situation ?

RTStyledLabel

by Peter UhnÃ¡k

Hi, I've added RTStyledLabel which supports TextEmphasis. RTGeneralExample>>styledLabel ~~~~~~~~~~~~~~ | v shape el all | v := RTView new. (shape := RTStyledLabel new) color: Color black. #(normal italic bold underlined struckOut) do: [ :each | el := shape emphasis: (TextEmphasis perform: each); elementOn: each. v add: el ]. all := shape emphasis: { TextEmphasis bold. TextEmphasis italic. TextEmphasis underlined}; elementOn: 'bold + italic + underlined'. v add: all. RTVerticalLineLayout on: v elements. v open ~~~~~~~~~~~~~~~~~~~~~ â Peter

Never mind, apparently I have to draw the underline manually.

Drawing underlined text on AthensCanvas

by Peter UhnÃ¡k

Hi, is it currently possible to draw underlined text onto AthensCanvas? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |font view| font := TextStyle defaultFont. font := font emphasized: TextEmphasis underlined emphasisCode. "<- underline does NOT work" "font := font emphasized: TextEmphasis bold emphasisCode." "<- bold works" view := AthensSceneView new. view scene: [:canvas | canvas surface clear: Color black. canvas setFont: font. canvas setPaint: Color red. canvas drawString: font asString. ]. view openInWindow. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I managed to find this previous discussion, however that is related more to Morphic http://forum.world.st/FreeType-fonts-and-underline-strikethrough-emphasis-t… https://pharo.fogbugz.com/f/cases/15362/ or maybe it's the same? This also doesn't work for StringMorph (as mentioned in the linked discussion), however TextMorph seems to work just fine.. Thanks, Peter

The graph below shows the chaotic behaviour with the first 100 terms of the sequence when parameter is around 3.6.

Re: [Pharo-users] Remember the math sequence ?

by Hilaire

Yes, it is a logistic map[1], which depending on r parameter value can be chaotic. You see it when the r parameter is dragged over 3. It should be possible to build graphic view seen in the wikipedia page bellow.
