在网上找了半天都没有发现用Powerbuilder调用Visual Graph控件的例子，就是北京图王公司的网站上都没有pb的例子。现在做了一个，供大家参考。

这是一个测试窗口w_test的代码，用PB11.5写的，在导入到PBL库之前先注册Visual Graph控件。

forward
global type w_test from window
end type
type cb_5 from commandbutton within w_test
end type
type cb_3 from commandbutton within w_test
end type
type vgctrl2 from olecustomcontrol within w_test
end type
type cb_4 from commandbutton within w_test
end type
type cb_2 from commandbutton within w_test
end type
type cb_1 from commandbutton within w_test
end type
type vgctrl1 from olecustomcontrol within w_test
end type
end forward

global type w_test from window
integer width = 2770
integer height = 1728
boolean titlebar = true
string title = "Untitled"
boolean controlmenu = true
boolean minbox = true
boolean maxbox = true
boolean resizable = true
long backcolor = 67108864
string icon = "AppIcon!"
boolean center = true
cb_5 cb_5
cb_3 cb_3
vgctrl2 vgctrl2
cb_4 cb_4
cb_2 cb_2
cb_1 cb_1
vgctrl1 vgctrl1
end type
global w_test w_test

end on

event open;vgctrl1.object.design(gs_hlp_path+"test.tbl")
vgctrl2.object.run(gs_hlp_path+"电脑设备.tbl")
