I'd like to be able to use dynamic tooltips, ie, change them on the fly based on the data being shown (specially in an elided header in a browser).

I added copy_tooltip in the same way that copy_label is implemented.

HOWEVER that means another flag() value is burned which could cause all kinds of trouble.

A better way to do this is to send a message to the widget before the toolti[p is shown. This avoids having to set the tooltip text over an over again. This should be part of the tooltip source file.

I'm not exactly sure what you mean by this.
I'm creating a widget then "building" the tooltip.
I *could* keep around an array of char* in my application and manually delete them but I shouldn't have to do that.
As mentioned this tooltip is for elided text...meains the widget itself is too small to display the full text so it displays a subset of the contents and the tooltip shows the real contents.

OK, I explained this badly. There are two issues: 1, making a tooltip copy the string, so you don't have to keep track of it is nice. But it is also not very diffigult to query the current tooltip, free it, then create a new tooltip. Not a big deal though.

The second issue is a problem that can arise if you continously change tooltips around. It is time consuming and may fragment memory by constantly allocating and deallocating memory, just in case the user may need a tooltip. It would be neat to get a TOOLTIP event just before an actual tooltip would be displayed, so I can allocate a ew string just once, when it is actually shown.

Devs: this STR is similar to #1944.

Side note: I'm making similar changes to 1.3, and was just
perusing this STR for reference, since its similar.

2.x Devs: note in OP's patch, copy_tooltip() docs still refer
to 'label()' and 'copy_label()'; be sure to correct. Also, note patch
introduces unusual indenting in the flags definition. Check carefully
when applying.
