Memleak in TStatusBar with GTK2

Original Reporter info from Mantis: Timm Thaler
  • Reporter name: Timm Thaler

Description:

If the panel text in a TStatusbar is updated with different content (e.g. timer, event counter...), the used program memory rises permanently.

Steps to reproduce:

put a TStatusBar with one Panel to a Form
put a Timer to that Form, set it to 10msec
update the statusbar every timer event with changing content

  Inc(cykl);
  If cykl >= 50 then cykl := 1;
  sts_bar.Panels[0].Text := StringOfChar('I', cykl);

see the used memory in the Taskmanager rising.

Additional information:

This happens with GTK2 widgetset in Linux, but not with WinApi widgetset in Windows.

It seems only to happen if the new content is different.
