Multiple icons in a column when in Book List view

[Frizzell]

Displaying multiple icons in one column seems elusive to me...

On the topic of using icons in columns (book list view), how many icons can be placed in one column and how many on the same row? So far, I haven't been able to create more than three rules for three icons in my 'Formats' column, and I had to double up a couple of icons to simulate two icons at once(See Screenshot). Is two icons the limit on the same row, or am I doing something wrong? I created icons for the four different eBook formats I use in my library, one each for epub, original_epub, mobi and pdf.

If anyone's an expert at creating rules for 'Column icons', I sure would like to see an example of how to make 'Four' rules for one column, and have all four display on the same row. Here is what I have so far:

RULE ONE:
Set the icon with no text of 'Format' to epub_original.png if the following conditions are met:
•If the Format column contains value: ORIGINAL_EPUB

RULE TWO:
Set the icon with no text of 'Format' to epub_pdficon.png if the following conditions are met:
•If the Format column contains value: PDF

RULE THREE
Set the icon with no text of 'Format' to epubicon.png if the following conditions are met:
•If the Format column contains value: EPUB


RULE FOUR: ***THIS ONE DOESN'T DISPLAY ICON***
Set the icon with no text of 'Format' to epub_mobiicon.png if the following conditions are met:
•If the Format column contains value: MOBI

Thanks,

AFAIK there's no limit on the number of icons that can be placed in a 'composed icon', I have one with six. I create integer columns on which to hang composed icons, so I use the 'composed icon with no text' option.

I think of a composed icon as a fixed array, with each slot assigned to condition. e.g. first slot gets a transparent_square if there's no epub else it gets an epub icon; second slot gets transparent_square if there's no pdf else it gets an pdf icon etc.

If you want a transparent square knock the .txt off the end of the attachment.

I understand what you are describing, and I take it that since you are creating multiple 'Integer' columns, then the primary answer to my question is, "Yes, you can only have two separate icons in one column."

Well, that certainly seems limiting as to the number of rules per column. Can you post a screenshot of your 'Book List' view so I can see exactly what you've done?

Thanks Red,
Frizzell

No, multiple icons on one Integer, screen shots from my Test library

Sorry for necroing this old thread.

If I have two conditions with true/false to show two icons simultaneously I will need 4 rules with composed icon sets?

Yes, if you want different icons for true and false.

I think it would be easier to use a single advanced rule that returns a compound icon. Something like this, but with the column names changed and the logic you want.

program:
	icon1 = if $$#myint != 'none' then 'cry-icon.png' else 'dictionary.png' fi;
	icon2 = if $$#mybool != 'true' then 'arrow-down.png' else 'arrow-up.png' fi;
	icon1 & ':' & icon2

EDIT: added image of results

	icon1 & ':' & icon2

Thank you so much again!

program:
	icon1 = if $$languages == 'englisch' then 'uk.png' else '' fi;
	icon2 = if $$#read == 'true' then 'ok.png' else  '' fi;
	icon3 = if $$#redl == 'true' then 'auto-reload.png' else '' fi;
	icon4 = if $$#toread == 'true' then 'reference.png' else '' fi;
	icon1 & ':' & icon2 & ':' & icon3 & ':' & icon4

I don't get language to work and not a 3x condition for #read (true, false, not defined).

I think you want something like this.

program:
	def add_icon(icon, val):
		if icon == '' then icon = val else icon = icon & ':' & val fi;
		return icon
	fed;

	icon = '';
	if $languages == 'eng' then icon = add_icon(icon, 'uk.png') fi;
	icon = add_icon(
		icon, 
		switch(
			$$#read,
			'true', 'ok.png',
			'false', 'false_icon.png',
			'unset_icon.png'));
	if $$#redl == 'true' then add_icon(icon, 'auto-reload.png') fi;
	if $$#toread == 'true' then add_icon(icon, 'reference.png') fi;
	return icon

Rationale:

• The language code check must look for the three-letter value as shown in this web page, not the full language name. If you want to indicate other languages then use a switch() as explained below.
• Using $$ (raw_field()) of a tristate boolean returns one of three values: "true", "false", and "none". These are not translated.
• The switch function is a good substitute for a sequence of if/then/elif/else that check string matches.
• It is best for performance not to have empty values separated by colons. The add_icon function takes care of that by adding the colon only if the icon string already has a value.

three-letter value

program:
	def add_icon(icon, val):
		if icon == '' then icon = val else icon = icon & ':' & val fi;
		return icon
	fed;

	icon = '';
	if $languages == 'eng' then icon = add_icon(icon, 'uk.png') fi;
	icon = add_icon(
		icon, 
		switch(
			$$#toread,
			'true', 'toread.png',
			'false', 'false.png',
			''));
	if $$#redl == 'true' then icon = add_icon(icon, 'redl.png') fi;
	if $$#read == 'true' then icon = add_icon(icon, 'ok.png') fi;
	return icon

Two modifications to your code. I had to add "icon =" to both bottom ones. It took me a while to figure this out.

I have an #annots column 'Long text, like comments, not in tag browser' for annotations and I want - like above - an icon if there are annoations.

program:
	def add_icon(icon, val):
		if icon == '' then icon = val else icon = icon & ':' & val fi;
		return icon
	fed;

	icon = '';
	if $languages == 'eng' then icon = add_icon(icon, 'uk.png') fi;
	icon = add_icon(
		icon, 
		switch(
			$$#toread,
			'true', 'toread.png',
			'false', 'false.png',
			''));
	if $$#formats == 'paper' then icon = add_icon(icon, 'paper.png') fi;
	if $$#read == 'true' then icon = add_icon(icon, 'ok.png') fi;
	if $$#readinglist != '' then icon = add_icon(icon, 'reading_list.png') fi;
	if $$#annots != '' then icon = add_icon(icon, 'annotations.png') fi;
	return icon

With this code I get the icon on every book.

I also tried

	if $$#annots == 'true' then icon = add_icon(icon, 'annotations.png') fi;

I don't get any annot icon

Some help much appreciated

The second template is checking that the column has a value of 'true.'

Here's what I would try:

program: if $$#annots then 'annotations.png' fi

[Wiggo]

thx, but doesn't work

[ownedbycats]

Dang, it works for me (though I used a different long-text column).

I placed your code in my list, not as a single one (don’t know how to say in a better way)
