1. ******在Patran下掛下拉菜單****** 通常我們不修改init.pcl文件，啟動init.pcl時而會執(zhí)行附帶的啟動文件p3prolog.pcl和p3epilog.pcl。如果這些文件存在，就會在init.pcl啟動前后裝載p3prolog.pcl（啟動前）和p3epilog.pcl（啟動后），所以這兩個文件是我們插入自定義命令的好地方。 !!PATH !!LIBRARY !!INPUT 在Patran安裝目錄下修改p3prolog.pcl，加入如下命令，例如： !!input mymenu.pcl #裝載菜單文件 ui_exec_function("mymenu","init") #當且僅初始化一次 !!input plateform.pcl #裝載對話框文件 2. ******** 下拉菜單程序編寫********* CLASS exercise FUNCTION init() /*初始化菜單*/ WIDGET menubar,menu,item1,item2,item3 /*定義控件變量*/ menu = uil_primary.get_menubar_id() /*獲取主菜單ID*/ menubar=ui_menu_create(menu,"exercise_menu","有限元分析") /*添加菜單*/ item1=ui_item_create(menubar,"ex_1","計算",FALSE) /*添加子菜單*/ item2=ui_item_create(menubar,"ex_2","導入文件",FALSE) /*添加子菜單*/ item3=ui_item_create(menubar,"ex_3","結(jié)束",FALSE) /*添加子菜單*/ END FUNCTION FUNCTION exercise_menu(item_name) /*菜單各項的響應函數(shù)*/ STRING item_name[] SWITCH(item_name) CASE("EX_1") write("Plate with a hole creating function") ui_exec_function("plateform","init") plateform.display() CASE("EX_2") write("cross pipes creating function") CASE("EX_3") write("slot modeling function") END SWITCH END FUNCTION END CLASS 3. *******彈出對話框程序編寫******* #include "appforms.p" CLASS plateForm /*定義控件變量*/ CLASSWIDE WIDGET form_id,dataBox1,dataBox2,dataBox3,@ apply_button,cancel_button,delete_button /*初始化對話框，必要的函數(shù)*/ FUNCTION init() real x_loc,y_loc /*創(chuàng)建對話框窗體ui_form_create(callback,x,y,position,width,height,label,[unused])*/ form_id=ui_form_create("",FORM_X_LOC,FORM_Y_LOC,"UL",FORM_WID_SML,FORM_HGT_FULL,"PLATE WITH A HOLE","") /*創(chuàng)建圖標*/ x_loc=FRAME_WID_SINGLE/2.-200*PIXEL_WID/2.+FORM_L_MARGIN y_loc=FRAME_T_MARGIN+INTER_WIDGET_SPACE /* ui_labelicon_create(parent,callback,x,y,label)*/ ui_labelicon_create(form_id,"",x_loc,y_loc,"platehole.icon") y_loc+=200.*PIXEL_HGT+DBOX_HGT_NO_LABOVE+INTER_WIDGET_SPACE /*創(chuàng)建輸入文本框ui_databox_create(parent,callback,x,y,label_length,box_length,width,height,label,value,label_above,datatype,num_vars)*/ dataBox1=ui_databox_create(form_id,"",FRAME_L_MARGIN,y_loc,SINGLE_SPACE*5.0,DBOX_WID_SINGLE*0.6,"r=",2.,FALSE,"REAL",1) y_loc+=DBOX_HGT_NO_LABOVE+INTER_WIDGET_SPACE dataBox2=ui_databox_create(form_id,"",FRAME_L_MARGIN,y_loc,SINGLE_SPACE*5.0,DBOX_WID_SINGLE*0.6,"w=",5.,FALSE,"REAL",1) y_loc+=DBOX_HGT_NO_LABOVE+INTER_WIDGET_SPACE dataBox3=ui_databox_create(form_id,"",FRAME_L_MARGIN,y_loc,SINGLE_SPACE*5.0,DBOX_WID_SINGLE*0.6,"h=",5.,FALSE,"REAL",1) y_loc+=DBOX_HGT_NO_LABOVE+INTER_WIDGET_SPACE*2 /*創(chuàng)建“應用”按鈕ui_button_create(parent, callback, x, y, width, height, label, [unused], highlight)*/ apply_button=ui_button_create(form_id,"apply_cb",BUTTON_HALF_X_LOC1,y_loc,BUTTON_WID_HALF,0,"應用",TRUE,TRUE) /*創(chuàng)建“取消”按鈕*/ cancel_button=ui_button_create(form_id,"cancel_cb",BUTTON_HALF_X_LOC2,y_loc,BUTTON_WID_HALF,0,"取消",TRUE,FALSE) y_loc+=DBOX_HGT_NO_LABOVE+INTER_WIDGET_SPACE /*創(chuàng)建“刪除”按鈕*/ delete_button=ui_button_create(form_id,"delete_cb",BUTTON_HALF_X_LOC1,y_loc,BUTTON_WID_HALF,0,"Delete",TRUE,FALSE) y_loc+=BUTTON_DEFAULT_HGT+FORM_B_MARGIN+INTER_WIDGET_SPACE ui_wid_set(form_id,"HEIGHT",y_loc) END FUNCTION /*窗體顯示，必要的函數(shù)*/ FUNCTION display() ui_form_display("plateForm") END FUNCTION /*“應用”按鈕響應處理函數(shù)*/ FUNCTION apply_cb() real r,w,h ui_wid_get(databox1,"VALUE",r) ui_wid_get(databox2,"VALUE",w) ui_wid_get(databox3,"VALUE",h) ui_form_hide("plateform") ui_writec("r =%f,w=%f,h=%f",r,w,h) END FUNCTION FUNCTION cancel_cb() ui_form_hide("plateform") END FUNCTION FUNCTION delete_cb() ui_form_delete("plateform") END FUNCTION END CLASS 4. C＋＋文件編譯處理 例如： d:\msc\patran2001r2\bin\cpp -id:/msc/patran2001r2/customization c:/uillist.pcl c:/uillist.cpp 5. 編程格式介紹 轉(zhuǎn)行繼續(xù)符：@ 分號分隔符：同C++：“；” 注釋多行：/*……*/ 注釋單行：“?！被蛘摺?” 計算表達式說明：用“`”（數(shù)字1鍵左邊的那個鍵）例如：Angle：`360/5`,或者用WRITE(10+20) 變量和常量 Integer（整型），Real（實數(shù)），Logical（TRUE和FALSE），String，Widget（控件，有個常量WIDGET_NULL） 變量的生命周期 Global 全局 Local 在函數(shù)內(nèi)，本地 Static 靜態(tài)，patran退出就消失 ClassWide 對一組函數(shù)可見，patran退出就消失 6. 指令文件管理 !! input file.pcl #編譯連接file.pcl,并將函數(shù)調(diào)入patran !!compile file.pcl into xxx.plb #編譯file.pcl,并存入plb庫中 !!library xxx.plb #將plb文件調(diào)入patran !!path Directory #指定打開文件的目錄 !!Trace option pcl #執(zhí)行確認 !!Debug option #保存注釋 !!options option #pcl環(huán)境設置 !!size code newsize #為編譯代碼區(qū)設置大小 !!clear global name #刪除全局變量定義 !!clear function name #刪除函數(shù)定義
