Question

I’m making an application that has to do with World of Warcraft.
To keep it short; You can pick talents that give you certain skills, in my application I added a talent calculator. Here you can pick talents, each talent has a description.
This is shown, like all spells and items, in a tooltip. For an example check here and hover over one of the talents.

So I want to make these tooltips too.
To do this I created a custom component following 2 guides

Guide 1 here

Guide 2 here

Now I made my component based on a panel. Made a package and installed it which all works.
It also shows in the list of components at design time.
Then I drag it onto my form, it gets automaticly included in the uses however…
When I try to run/build/compile my application I get an error and it says:
Cannot resolve unit name 'Tooltip'
and I have no idea how to fix this.

There are plenty tutorials that show you how to make a custom component but none of them talks about this problem. Am I doing something wrong?

Any advice will be very welcome 🙂

Answer 1

You have to setup the common library path and search path.

Open from IDE-Menu Tools\Options

Walk to Environment Options\Delphi Options\Library

1. Edit Library Path and add the Path containing the component compiled libraries (.dcu files) or the path containing the component source files

2. Edit Search Path and add the Path containing the component source files (this is optional but helpful when debugging)

You have to repeat theses steps for all platforms your component will be used. But if you put the library path to compiled libraries, you have to ensure the right .dcu for the platforms.
