If I have TIcon or TBitmap component, how can I load a standard icon
using its name according to Icon Naming Convention?
For example, there is an icon called "dialog-information" (which look
depends on current icon theme), how can I display this icon in my
Lazarus program for GTK2 or Qt?

Thank you in advance.

Some more information. What I am looking for is implemented in this
function:
MessageDlg('Confirmation',mtInformation, mbOKCancel, 0);
Depending on the value of TMsgDlgType (mtInformation) the dialog shows
one of the standard icons (dialog-information in this case).
Cannot find the module with the implementation of this code to see how
it was made. Any ideas?

Even by clicking the MessageDlg while pressing Ctrl?

I did not know about Ctrl+click, but it seems the same as Find
Declaration in the popup menu. Unlike Delphi, Lazarus brings exactly
declaration, just a single header line, and any further search gives
no results.

Looks like I have found something useful. After jumping by Find
Declaration, there is another possibility to get further - Find ->
Procedure Jump.  It does the trick.
