Description
Within graphs
The Label property specifies the label of an axis of the graph.
Within ListView and TreeView controls
The Label property specifies the label associated with a ListViewItem
or TreeViewItem object.You cannot manipulate items in TreeView controls
in a painter. You must write scripts to add items to a TreeView.
Usage
In a painter
To specify an Axis label in a graph control:
-
Display the Axis tab page of the graph
control’s Properties view. -
Select the desired axis from the Axis drop-down
list. -
Enter the label text in the Label text field.
To specify labels for items in a ListView control:
-
Display the Items tab page of the ListView
control’s Properties view. -
For each item, enter label text in the appropriate
Text field.
In scripts
The Label property takes a string value. The following example
sets text for the label on the Values axis of graph gr_1.
|
1 |
gr_1.Values.Label = 'Lawsuits per 1000' |
To add or insert an item with a label into a ListView control,
use the AddItem or InsertItem functions.
For example, this line adds an item to ListView control lv_1,
specifying the label and picture index for the item:
|
1 |
lv_1.AddItem ( "Oranges", 1) |
To change the label, get the item from the ListView and set
the item’s Label property:
|
1 |
ListViewItem lvi |
|
1 |
lv_1.GetItem(4, lvi) |
|
1 |
lvi.Label = "Apples" |
|
1 |
lv_1.SetItem(4, lvi) |
To add or insert items in a TreeView control, use the InsertItem, InsertItemFirst, InsertItemLast,
or InsertItemSort functions.
