Web components changes

Modifications to consider when using web components.

Only SIZEPOLICY=FIXED is supported for WEBCOMPONENT fields

When defining a WEBCOMPONENT field in the form, the only valid option for the SIZEPOLICY attribute is FIXED. This is by the way the default for WEBCOMPONENT fields.

For more details, see Controlling the web component layout.

fglrichtext: New implementation

Up to FGLGWS version 3.10.09 (WCG 1.00.11), the fglrichtext built-in web component was based on draft.js Rich Text Editor Framework.

Starting with FGLGWS 3.10.11 (WCG 1.00.12), the fglrichtext web component is implemented with the quilljs Rich Text Editor.

Available features and configuration options have changed.

For more details, see The fglrichtext web component.

fglrichtext: Support of emojis

Starting with FGLGWS version 3.10.13 (WCG 1.00.13), the emoji toolbar option allows users to include an emoji in the text of an fglrichtext web component.

Important:

Since emojis are Unicode characters and not plain images, your application needs to use UTF-8. Emojis rendering will differ depending on the device you're running it on. You might need to install fonts that handle emoji characters as well if your device doesn't handle it.

For more details, see Configuring the toolbar.

fglrichtext: Defining a default font

Starting with FGLGWS version 3.10.16 (WCG 1.00.15), a default font family and font size can be specified for a fglrichtext web component with new properties.

For more details, see Specifying the default font.

fglrichtext: Localizing texts

Starting with FGLGWS version 3.10.16 (WCG 1.00.15), it is possible to localize the texts used by the fglrichtext web component.

Several properties have been added to the fglrichtext web component, to define the strings for each toolbar button tooltips, combobox items, and popup dialog labels.

For more details, see Localizing rich text component strings.

fglsvgcanvas: Mouse hovering events

Starting with FGLGWS version 3.10.11 (WCG 1.00.12), the fglsvgcanvas built-in web component supports new properties to detect onmouseover / onmouseout mouse hovering SVG events, and trigger ON ACTION blocks.

For more details, see The fglsvgcanvas web component.

fglsvgcanvas: title() and createChars() functions

Starting with FGLGWS version 3.10.18 (WCG 1.00.16), the fglsvgcanvas library provides the title() function to create a title SVG element, and the createChars() function to create a text node.

For more details, see fglsvgcanvas: SVG drawing module.

fglgallery: Aspect ratio for image elements

Using FGLGWS version 3.10.18 (WCG 1.00.16), image elements are now aligned properly by using the same size, in case if picture resources have different sizes.

By default, the images are displayed with a square (1:1) aspect ratio. To define a different aspect ratio, the fglgallery library provides the setImageAspectRatio() function.

For more details see fglgallery image aspect ratio handling.

fglgallery: Custom CSS file handling

Starting with FGLGWS version 3.10.18 (WCG 1.00.16), to avoid missing resource errors in web viewers, the custom CSS file $FGLDIR/webcomponents/fglgallery/css/fglgallery-custom.css is no longer included by default in the fglgallery.html file.

If you want to provide you own CSS file for fglgallery, uncomment the <link /> line in fglgallery.html.

Note also that CSS names have changed, since the HTML content of fglgallery has been reviewed for images aspect ratio handling.
