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。
|
--------------------------------- li_cenx,li_xminusy,li_wminush // 取出当前窗口的坐标值、大小值 // 设置窗体关闭前的动画效果 |
| window.height = li_height - 2*(li_gd - li_y) next case 5 // closetype = 5,从左右向中间挤压逐渐消失 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,从左上->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,从右下->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,从右上->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,从左下->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,从四面到中间 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 ************************ // 调用该函数在窗体的 closequery 事件中 gf_closequery (w_main,mod(integer(string(now(),"ss")),11)) |
上面是关闭时的效果,窗体打开时的动态效果的语句跟上面的差不多,在此就不写啦,如果有需要的可以告诉我,我单独发送。谢谢。
