Icon property confusion |
Tue, Jun 14 2016 8:38 AM | Permanent Link |
Matthew Jones | I am trying to make a "tab bar" based on the TToolbar component. It
seems fine, apart from the UpdateAutoWidth because I want the layout to be "Caption [icon]" for each tab. The elements are therefore TopLeft, consume right. That's fine, but the code to determine the width is just not behaving at all. I tried to work out if the icon is assigned or not by testing the FIcon property, but it seems not to be working at run-time. Is the serialisation affecting this somehow? Anyone got clues? I'm not entirely sure the FCaptionElement is always actually fitting the text properly either. procedure TIndexBarButton.UpdateAutoWidth; var TempWidth: Integer; begin BeginUpdate; try if FAutoWidth then begin TempWidth:=(Width-ClientWidth); if FCaptionElement.Visible then Inc(TempWidth,FCaptionElement.Width); if FIcon = '' then // if FFontIconElement.Content <> '' then Inc(TempWidth,FIconElement.Width); Constraints.Max.Width:=TempWidth; Constraints.Min.Width:=TempWidth; end else begin Constraints.Max.Width:=0; Constraints.Min.Width:=0; end; finally EndUpdate; end; end; |

With the default TToolBarButton class, the icons are assumed to be a fixed size, determined by the icon definition in the icon library. << Is the serialisation affecting this somehow? >> No. Tim Young Elevate Software www.elevatesoft.com |

I will experiment further at some point, and perhaps post the whole thing for someone else to help with. Having tabs standalone is really nice. (I chose the name "IndexTab" to show it is more like an index, due to the "conflict" with the Page control which has its own Tab controls.) |

<< No, I am happy with it constant. But even making it a constant doesn't work for me. >> You don't need to make it a constant - the "constant" is the defined width for the icon in the icon library. << I will experiment further at some point, and perhaps post the whole thing for someone else to help with.

So tab1 might be apples, and tab2 oranges. Click on one and the database filter changes, but no need to change the grid itself. I actually have 5 different types, and at the moment am just re-parenting the grid, but for the latest form I figured it better to do a proper component. |

More than happy to adopt yours though! 8-) (It might be worth asking what people want after 2.05 is out, but you probably already know...) |
