Setting label font size in Roassal2

Hi guys,

I was able to create a world map rendering circles in the country centroids.

However, labelling such circles is problematic, specially in the case of Europe where many countries are small and close enough each other.

See the attachment picture,

Is there a way to set up the label size?

This is what I am doing:

    self filteredTerritories: (self itemsByFeature: 'country') asBag sortedElements.
    gbViewBuilder := RTCountryMapBuilder newWithCentroids: self filteredTerritories.
    gbViewBuilder countries: RTMapBuilder countries.
    gbViewBuilder centroids: self filteredTerritories named: [ : assoc | assoc key ].
    gbViewBuilder centroids shape
        size: [ : countryAssoc | countryAssoc value ];
        if: [ :c | c value < 10 ] fillColor: (Color green alpha: 0.5);
        if: [ :c | c value >= 10 and: c value < 50 ] fillColor: (Color yellow alpha: 0.5);
        if: [ :c | c value >= 50 ] fillColor: (Color red alpha: 0.5);
        labelledAs: [ : c | self centroidLabel: c ].

    gbViewBuilder color: Color veryVeryLightGray.
    gbViewBuilder scale: 1.5.
    gbViewBuilder withPopup.
    gbViewBuilder build.
    gbViewBuilder view.

Cheers,

Hernán

Re: Setting label font size in Roassal2

Hi Hernan,

Yes, label size can be easily set up. Check this:

-=-=-=-=-=-=-=-=-=-=-=-=
v := RTView new.

shape := RTLabel new height: #yourself.
labels := shape elementsOn: (5 to: 30 by: 5).
v addAll: labels.

RTFlowLayout on: labels.

v
-=-=-=-=-=-=-=-=-=-=-=-=

I suspect that in your case, you need to keep the size of the label when you zoom in. Is that correct?
If this is the case, then you may need to fix the elements:
-=-=-=
v := RTView new.

shape := RTLabel new height: #yourself.
labels := shape elementsOn: (5 to: 30 by: 5).
labels do: #setAsFixed.
v addAll: labels.

RTFlowLayout on: labels.

v
-=-=-=-=

But you cannot scroll them. Let me know what you exactly need.

Re: Setting label font size in Roassal2

Hi Alex,

I just added a method to set font size and color:

RTShapeBuilder>>labelledAs: aBlock size: aValue color: aColor

    | label oldShape |
    label := RTLabel new text: aBlock.
    label height: aValue.
    label color: aColor.
    oldShape := shape.
    shape := RTCompositeShape new.
    shape add: oldShape.
    shape add: label.

    shape vertical.
    shapeInitializer rtValue: shape.

    ^ label

I will take a look to the examples you wrote.

Re: Setting label font size in Roassal2

It looks like to be redundant with RTShapeBuilder>>fontSize:

For example:

-=-=-=-=-=-=-=-=

b := RTMondrian new.

b shape label

fontSize: #yourself;

color: [ :v | Color random ].

b nodes: (1 to: 40).

b layout grid.

-=-=-=-=-=-=-=-=

Cheers,

Alexandre
