What i need
Does LVS_EX_LABELTIP for Win32 ListView automatically implement showing tooltips for truncated items (i.g."Hello, W...")? Like style LVS_EX_CHECKBOXES which works "out of the box".

Or is it developers responsibility? (From reading MSDN i assume that it should work out of the box: "If a partially hidden label in any list view mode lacks tooltip text, the list-view control will unfold the label").

Edit: my ListView must have LVS_REPORT

What I have tried:

i tried to set all styles that rely to this topic.
i've searched the google, but can't see any example of "out of the box" being proven.

I wouldn't worry about it. I would try it and find out and then deal with the results.

Solution 1

the label tip has some standard amount of characters, so a lengthly text gets truncated. Your flag is to override that default behaviour.

"If a partially hidden label in any list view mode lacks tooltip text, the list-view control will unfold the label. If this style is not set, the list-view control will unfold partly hidden labels only for the large icon mode." It means that a label already must exist, and only the full display will enforced.

See MSDN to read the fineprint.

i am sorry, but for me it is really hard to understand what you wrote here. "The label tip has some standard amount of characters" - aren't labels truncated based on their width relative to column width?
"Your flag is to override that default behaviour" - What does it actually override? A lengthly text won't be truncated anymore?
