TSvgIconImageCollection and Gettext

Gettext for Delphi has two procedures TranslateComponent and RetranslateComponent, which are called when a form is created and when the UI language changes. These procedures translate all string properties of all components on a form. Since each SVG Icon has a Name property, Gettext tries to translate the icon names for all icons in the collection, which is normally not what we want.

• You may want to access the icon by name instead of by index, so you don't want the name to change.
• Assigning the names of all icons at runtime causes a massive slowdown of the application during initialization.
  See https://github.com/EtheaDev/SVGIconImageList/issues/197.
• There is another side effect of Gettext which translates the item names in TVirtualImageList.
  See: https://github.com/EtheaDev/SVGIconImageList/issues/198

There are two possible solutions for this problem:

1. Don't assign a name to your svg icon items. If they don't have a name, they won't be translated by accident.
2. Add TP_GlobalIgnoreClass(...); instructions to your .dpr file before any forms are created or to the initialization section of any unit that is called before Gettext does it's magic. There are two alternatives:

• This excludes all TSVGIconImageCollections and TVirtualImageLists from translation.

  TP_GlobalIgnoreClass(TSVGIconImageCollection);
  TP_GlobalIgnoreClass(TVirtualImageList);
  

• This excludes the ImageName property of all objects, since ImageName should not be translated in any component.

  TP_GlobalIgnoreClassProperty(TObject,'ImageName');`
  

Choose whichever approach suits you best.
