窗体动态效果的实现_2008源码下载_flash源码

最近用pb做了一个触摸屏的程序，项目组要求窗口显示关闭的时候有点动态效果，于是我就写了如下的程序，供大家参考借鉴。

---------------------------------
// 实现关闭窗体时的动态效果
// -------------------------------
// 函数名：gf_closequery
// 参数说明:
//         window    window类型,调用窗口的名字
//         closetype integer类型,窗口关闭方式,value = 0~10
// -------------------------------
// 申明局部变量
int li_x ,li_y,li_width,li_height,li_ceny,li_cenx,li_xminusy,li_wminush
Integer li_gd

// 取出当前窗口的坐标值、大小值
li_x = window.x
li_y = window.y
li_width = window.width
li_height = window.height

// 设置窗体关闭前的动画效果
// 关键是看哪个值发生了变化——x、y、h、w
CHOOSE CASE closetype
CASE 0      // closetype = 0,从下到上逐渐消失
for li_gd = li_height to 0 step -1
   window.height = li_gd
   window.show()
next
CASE 1      // closetype = 1,从上到下逐渐消失
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

for li_gd = li_width to 0 step -1
   window.width = li_gd
next
