第二篇matlab app 学习笔记：新建选项卡组TabGroup、面板Panel、按钮Button、表UITable
一、添加UITable表删除操作
在app.Tab_datamanage页面，在app.panel_datamanage面板内新增一个面板app.panel_datamanage2，在面板内增加三个按钮“删除行”（app.btn_deleterow_data）、“删除列”（app.btn_deletecol_data）、“清空”（app.btn_deleteall_data）。
（一）增加“删除行”（app.btn_deleterow_data）的回调函数
回调函数的思路是先获取用户选择selects=app.UITable_data.Selection，再筛选出选择的行uniquerows=unique(rows)，最后将这些行的值设置为空app.UITable_data.Data(uniquerows,:)=[];同时将行名的对应部分也清空（如有）app.UITable_data.RowName(uniquerows)=[];。
function btn_deleterow_dataButtonPushed(app, event)
try
selects=app.UITable_data.Selection;%获取用户选择的单元格列表（二维数组，选择模式是cell）
if ~isempty(selects)
rows=selects(:,1);%获得行数组
uniquerows=unique(rows);%去除重复项
app.UITable_data.Data(uniquerows,:)=[];%将选择的行的数据清空，即删除行
if ~isempty(app.UITable_data.RowName)
app.UITable_data.RowName(uniquerows)=[];%删除对应的行名（如有）
end
end
catch ME
errordlg(ME.message);%如果发生错误，弹出错误提示框
end
end（二）增加“删除列”（app.btn_deletecol_data）的回调函数
回调函数的思路与上面的删除行一致。代码如下：
function btn_deletecol_dataButtonPushed(app, event)
try
selects=app.UITable_data.Selection;
if isempty(selects)
return;
end
selectedColumns = selects(:,2);%获取列数组
uniqueColumns = unique(selectedColumns)';%去重并排序
app.UITable_data.Data(:,uniqueColumns)=[];%删除列
if ~isempty(app.UITable_data.ColumnName)
app.UITable_data.ColumnName(uniqueColumns)=[];%删除列名
end
catch ME
errordlg(ME.message);
end
end（三）增加“清空”（app.btn_deleteall_data）的回调函数
代码如下：
function btn_deleteall_dataButtonPushed(app, event)
app.UITable_data.Data=[];
end二、添加UITable列查找操作
当UITable中的列很多时，要查找某个参数的数据会比较困难，因此增加按列名查找的功能。
在app.panel_datamanage面板内新增一个面板app.panel_datamanage3，在面板内增加编辑字段（文本）（查找输入框）app.editfield_findcol_data，和按钮“查找”app.btn_findcol_data。
回调函数有两个：
- 编辑字段（文本）（查找输入框）app.editfield_findcol_data的ValueChanged回调，当用户输入完成点击回车时生效；
- “查找”app.btn_findcol_data的回调函数，用户点击时生效，该回调直接调用编辑字段的回调即可。
代码如下：
function editfield_findcol_dataValueChanged(app, event)
%通过lower将用户输入的字符和列名转化为小写，在列名中查找用户输入的列名，并将表的选择置于列的第一个cell
find_value = lower(app.editfield_findcol_data.Value);%获取用户输入并转化为小写
cols=lower(app.UITable_data.ColumnName);%获取表列名并转化为小写
try
col = find(contains(cols, find_value));%查找列名所在的位置，contains返回大小与cols相同的逻辑数组，find找的其中为true的值的位置
scroll(app.UITable_data, 'column', col);%将UITable按列滚动到查找到的列处
app.UITable_data.Selection=[1,col];%将UITable的选择设置为查到到的列的第一个cell
catch ME
errordlg(ME.message);
end
end
function btn_findcol_dataButtonPushed(app, event)
app.editfield_findcol_dataValueChanged;%调用现有回调函数
end三、添加单元格内容显示控件
由于UITable控件默认显示小数位数为4位，本可以通过format设置显示格式，但大量数据显示全部小数位数并不利于数据处理，我们往往只是需要查看特定单元的实际数值，就可以通过添加一个编辑字段控件来显示用户选择的table表格中cell对应的数据。
在app.panel_datamanage面板内新增一个面板app.panel_datamanage4，在面板内增加编辑字段（数值）app.editfield_findcol_data，和按钮“查找”app.editfield_selectedcell_data。
这里添加的回调函数是UITable的回调，即当用户选择发生变化后的回调。代码如下：
function UITable_dataSelectionChanged(app, event)
selection = app.UITable_data.Selection;%获取用户选择的单元格
last_cell=selection(end,:);%选择最后一个单元格
app.editfield_selectedcell_data.Value= table2array(app.UITable_data.Data(last_cell(1),last_cell(2)));%将单元格的信息显示在editfield上
end四、添加撤销操作
当我们编辑表格等内容时，往往存在错误操作需要返回上一步的情况，这时候撤销操作显得尤为重要，二小操作的步骤如下：
1.将用户的操作即数据记录下来
涉及UITable的操作，在本页面有：删除行、删除列、清空、编辑单元格。我们为每一个操作增加一个记录更改前数据和更改后数据的记录，并记录在程序的属性logOperation。
在app中增加三个参数：
MaxUndoLevels = 5; % 最大撤销步数
LogBuffer = {}; % 操作日志记录
CurrentIndex = 0 ; % 当前操作位置删除行在原按钮的回调函数中增加代码后如下：
function btn_deleterow_dataButtonPushed(app, event)
%前三行为增加代码，记录更改前的表数据
preData=app.UITable_data.Data;
preData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
preData.Properties.RowNames=app.UITable_data.RowName;%存储行名
try
selects=app.UITable_data.Selection;%获取用户选择的单元格列表（二维数组，选择模式是cell）
if ~isempty(selects)
rows=selects(:,1);%获得行数组
uniquerows=unique(rows);%去除重复项
app.UITable_data.Data(uniquerows,:)=[];%将选择的行的数据清空，即删除行
if ~isempty(app.UITable_data.RowName)
app.UITable_data.RowName(uniquerows)=[];%删除对应的行名（如有）
end
end
%后面三行增加的代码记录修改后的数据
newData=app.UITable_data.Data;
newData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
newData.Properties.RowNames=app.UITable_data.RowName;%存储行名
%接下来通过logOperation函数记录变更类型、变更对象、原数据，新数据到LogBuffer
app.logOperation('tableEdit','UITable_data',preData,newData);
%由于用于有了新的操作，将记录操作步骤置为当前
app.CurrentIndex=height(app.LogBuffer);
catch ME
errordlg(ME.message);%如果发生错误，弹出错误提示框
end
end删除列在原按钮的回调函数中增加代码后如下：
% Button pushed function: btn_deletecol_data
function btn_deletecol_dataButtonPushed(app, event)
preData=app.UITable_data.Data;
preData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
preData.Properties.RowNames=app.UITable_data.RowName;%存储行名
try
selects=app.UITable_data.Selection;
if isempty(selects)
return;
end
selectedColumns = selects(:,2);%获取列数组
uniqueColumns = unique(selectedColumns)';%去重并排序
app.UITable_data.Data(:,uniqueColumns)=[];%删除列
if ~isempty(app.UITable_data.ColumnName)
app.UITable_data.ColumnName(uniqueColumns)=[];%删除列名
end
newData=app.UITable_data.Data;
newData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
newData.Properties.RowNames=app.UITable_data.RowName;%存储行名
app.logOperation('tableEdit','UITable_data',preData,newData);
app.CurrentIndex=height(app.LogBuffer);
catch ME
errordlg(ME.message);
end
end清空在原按钮的回调函数中增加代码后如下：
function btn_deleteall_dataButtonPushed(app, event)
preData=app.UITable_data.Data;
preData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
preData.Properties.RowNames=app.UITable_data.RowName;%存储行名
app.UITable_data.Data=[];
newData=app.UITable_data.Data;
newData.Properties.VariableNames=[];%存储列名
newData.Properties.RowNames=[];
app.logOperation('tableEdit','UITable_data',preData,newData);
app.CurrentIndex=height(app.LogBuffer);
end编辑单元格的回调时UITable的回调函数，代码如下：
% Cell edit callback: UITable_data
function UITable_dataCellEdit(app, event)
indices = event.Indices;%编辑单元格的行列数组，如[1,2]为第1行第2列
preData=event.PreviousData;%修改前的单元格数据
preData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
preData.Properties.RowNames=app.UITable_data.RowName;%存储行名
pretabledata=app.UITable_data.Data;%当前表数据赋值给修改前的数据存储
pretabledata(indices(1),indices(2))=table(preData);%将修改前的数据存储中已经修改过的数据改回原来的值
newData = app.UITable_data.Data;%保存新的数据
newData.Properties.VariableNames=app.UITable_data.ColumnName;%存储列名
newData.Properties.RowNames=app.UITable_data.RowName;%存储行名
app.logOperation('tableEdit','UITable_data',pretabledata,newData);%存储修改类型、控件名称、原数据、新数据到LogBuffer
app.CurrentIndex=height(app.LogBuffer);
endlogOperation函数如下：
function logOperation(app, actionType, targetId,preData,newData)
app.LogBuffer = [app.LogBuffer; {datetime('now'), actionType, targetId, preData,newData}];%在LogBuffer 下一行增加新的操作数据
app.CurrentIndex = height(app.LogBuffer);%因为人为修改了数据，将操作顺序的记录置为当前
if height(app.LogBuffer) > app.MaxUndoLevels%如果LogBuffer 数量超过了预定的长度（允许撤销的次数），将第一个操作置空删除
app.LogBuffer(1,:) = [];
end
end2.建立工具栏和撤销、重做按钮
在UIFigure下新家一个工具栏toolbar，并添加按钮工具app.PushTool_undo和app.PushTool_redo。
PushTool_undo用于撤销操作，PushTool_redo用于重做操作。
对PushTool_undo添加回调函数：
% Callback function: PushTool_undo
function PushTool_undoClicked(app, event)
if app.CurrentIndex > 0
app.undoAction(app.CurrentIndex);%调用undo函数
if app.CurrentIndex>1
app.CurrentIndex = app.CurrentIndex - 1;%将序号调整到前一步操作
end
end
end
function undoAction(app,index)
if index>=1&&index<=height(app.LogBuffer)
op = app.LogBuffer(index, :);%获取当前操作序号的记录
switch op{2}
case 'tableEdit'%判断修改类型，如果为tableEdit，表编辑，我自定义的
app.(op{3}).Data = op{4};%将存在的原数据加载到表app.(op{3})是通过控件名称调用控件的方式即app.('UITable_data')
app.(op{3}).ColumnName=op{4}.Properties.VariableNames;%将原列名赋值给UITable
app.(op{3}).RowName=op{4}.Properties.RowNames;%将原行名赋值给UITable
case 'textInput'
app.(op{3}).Value = op{4};
% 可扩展其他控件类型
end
end
end对PushTool_redo添加回调函数：
% Callback function: PushTool_redo
function PushTool_redoClicked(app, event)
if app.CurrentIndex > 0
app.redoAction(app.CurrentIndex);
if app.CurrentIndex<height(app.LogBuffer)
app.CurrentIndex = app.CurrentIndex + 1;
end
end
end
function redoAction(app,index)
if index>=1&&index<=height(app.LogBuffer)
op = app.LogBuffer(index, :);
switch op{2}
case 'tableEdit'
app.(op{3}).Data = op{5};%将新数据重新赋值给UITable
app.(op{3}).ColumnName=op{5}.Properties.VariableNames;
app.(op{3}).RowName=op{5}.Properties.RowNames;
case 'textInput'
app.(op{3}).Value = op{5};
% 可扩展其他控件类型
end
end
