窗體動態效果的實現

最近用pb做了一個觸摸屏的程序，項目組要求窗口顯示關閉的時候有點動態效果，于是我就寫了如下的程序，供大家參考借鑒。
-------------------------------------------------------------------------------------
// 實現關閉窗體時的動態效果
// ---------------------------------------------------------
// 函數名：gf_closequery
// 參數說明:
// window window類型,調用窗口的名字
// closetype integer類型,窗口關閉方式,value = 0~10
// ---------------------------------------------------------
// 申明局部變量
int li_x ,li_y,li_width,li_height,li_ceny,li_cenx,li_xminusy,li_wminush
integer li_gd
// 取出當前窗口的坐標值、大小值
li_x = window.x
li_y = window.y
li_width = window.width
li_height = window.height
// 設置窗體關閉前的動畫效果
// 關鍵是看哪個值發生了變化——x、y、h、w
choose case closetype
case 0 // closetype = 0,從下到上逐漸消失
for li_gd = li_height to 0 step -1
window.height = li_gd
window.show()
next
case 1 // closetype = 1,從上到下逐漸消失
for li_gd = li_y to li_height+li_y step 1
window.y = li_gd
window.height = li_height+li_y - li_gd
window.show()
next
case 2 // closetype = 2,從右到左逐漸消失
for li_gd = li_width to 0 step -1
window.width = li_gd
next
case 3 // closetype = 3,從左到右逐漸消失
for li_gd = li_x to li_x+li_width step 1
window.x = li_gd
window.width = li_x+li_width - li_gd
window.show()
next
case 4 // closetype = 4,從上下向中間擠壓逐漸消失
li_ceny = li_y+li_height/2
for li_gd = li_y to li_ceny step 1
window.y = li_gd
window.height = li_height - 2*(li_gd - li_y)
next
case 5 // closetype = 5,從左右向中間擠壓逐漸消失
li_cenx = li_x+li_width / 2
for li_gd = li_x to li_cenx step 1
window.x = li_gd
window.width = li_width - 2*(li_gd - li_x)
next
case 6 // closetype = 6,從左上->右下
for li_gd = li_y to li_height+li_y step 1
window.y = li_gd
window.height = li_height+li_y - li_gd
if window.x < li_x + li_width then
window.x = li_x + (li_gd - li_y)
else
window.x = li_x + li_width
end if
if window.width > 0 then
window.width = li_x+li_width - window.x
else
window.width = 0
end if
next
window.x = li_x + li_width
window.y = li_height+li_y
window.width = 0
window.height = 0
window.show()
case 7 // closetype = 7,從右下->左上
for li_gd = li_height to 0 step -1
window.height = li_gd
if window.width > 0 then
window.width = li_width - (li_height - li_gd)
else
window.width = 0
end if
next
window.x = li_x
window.y = li_y
window.width = 0
window.height = 0
window.show()
case 8 // closetype = 8,從右上->左下
for li_gd = li_y to li_height+li_y step 1
window.y = li_gd
window.height = li_height+li_y - li_gd
if window.width > 0 then
window.width = li_width - (li_gd - li_y)
else
window.width = 0
end if
next
window.x = li_x
window.y = li_height+li_y
window.width = 0
window.height = 0
window.show()
case 9 // closetype = 9,從左下->右上
for li_gd = li_x to li_x+li_width step 1
window.x = li_gd
window.width = li_width +li_x -li_gd
if window.height > 0 then
window.height = li_height -(li_gd - li_x)
else
window.height = 0
end if
next
window.x = li_x+li_width
window.y = li_y
window.width = 0
window.height = 0
window.show()
case 10 // closetype = 10,從四面到中間
li_ceny = li_y+li_height/2
li_cenx = li_x+li_width / 2
for li_gd = li_y to li_ceny step 1
window.y = li_gd
window.height = li_height - 2*(li_gd - li_y)
if window.x < li_x + li_cenx then
window.x = li_x + (li_gd - li_y)
else
window.x = li_x + li_cenx
end if
if window.width > 0 then
window.width = li_width - 2*(li_gd - li_y)
else
window.width = 0
end if
next
window.x = li_cenx
window.y = li_ceny
window.width = 0
window.height = 0
window.show()
case else
window.show()
window.width = li_width
window.height = li_height
window.x = li_x
window.y = li_y
end choose
return 0
***********************************
// 調用該函數在窗體的 closequery 事件中
gf_closequery (w_main,mod(integer(string(now(),"ss")),11))

上面是關閉時的效果，窗體打開時的動態效果的語句跟上面的差不多，在此就不寫啦，如果有需要的可以告訴我，我單獨發送。謝謝。
