| 25 | + | ## Usage | |
| 26 | + | ||
| 27 | + | In the form's OnShow (or maybe OnCreate) create the object like this: | |
| 28 | + | ||
| 29 | + | ``` pascal | |
| 30 | + | uses | |
| 31 | + | win32taskbarprogress; | |
| 32 | + | ||
| 33 | + | procedure TForm1.FormShow(Sender: TObject); | |
| 34 | + | begin | |
| 35 | + | GlobalTaskbarProgress:= TWin7TaskProgressBar.Create; | |
| 36 | + | end; | |
| 37 | + | ``` | |
| 38 | + | ||
| 39 | + | And then call properties of this object like this: | |
| 40 | + | ||
| 41 | + | ``` pascal | |
| 42 | + | //to change state: none, green, yellow, red, floating | |
| 43 | + | GlobalTaskbarProgress.Style:= TTaskBarProgressStyle(ComboBoxStyle.ItemIndex); | |
| 44 | + | ||
| 45 | + | //to change progress value 0 to 100 | |
| 46 | + | GlobalTaskbarProgress.Progress:= Edit1.Value; | |
| 47 | + | ``` | |
| 48 | + | ||
| 49 | + | Author tried to initialise the object in the "initialization" part of win32taskbarprogress, but failed, maybe because the Application.Handle is not initialised so early. | |
