常用對話方塊（四）

1.輸入對話方塊 inputdlg

answer = inputdlg(prompt)

answer = inputdlg(prompt,dlg_title)

answer = inputdlg(prompt,dlg_title,num_lines)

answer = inputdlg(prompt,dlg_title,num_lines,defAns)

answer = inputdlg(prompt,dlg_title,num_lines,defAns,options)

建立一個輸入對話方塊，prompt為提示字串，title為對話方塊名稱，num_line為顯示的行數，defAns為預設的數值

%輸入對話方塊

inputdlg("請輸入使用者名稱：","找回密碼");

inputdlg({"使用者名稱","密碼"},"登入名");

使用元胞陣列

顯示3行

有預設值

inputdlg({"x(1)","x(2)"},"橫座標設定",1,{"0","10"});

2.目錄選擇對話方塊 uigetdir

folder_name = uigetdir

folder_name = uigetdir(start_path)

folder_name = uigetdir(start_path,dialog_title)

start_path為預設的路徑，dialog_title為對話方塊名稱

3.列表選擇對話方塊 Listdlg

[Selection,ok] = listdlg("ListString",S)

selection代表選項的索引值，OK代表單擊ok返回1，單擊cancel返回0；

%列表選擇對話方塊

[sel,ok]=listdlg("liststring",{"自控原理","自動檢測","微控制器嵌入式","化工原理","軟體你基礎"},...

"listsize",[180 80],"OkString","確定","CancelString","取消",...

"promptstring","課程科目","name","選擇你所感興趣的科目（多選）","selectionmode","multiple");

selectmode屬性有2個選項single 和multiple
