Gui table with dropdown problem
显示 更早的评论
Hi! I am trying to create a GUI with table that includes first column with a dropdown list in each cell. But I keep getting an error. The opening fuction for the uitable is below:
% --- Executes just before GuiTable01 is made visible.
function GuiTable01_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to GuiTable01 (see VARARGIN)
% Choose default command line output for GuiTable01
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
Nrows = 40; Ncols = 6;
Data_init0 = cell(Nrows,Ncols);
set(handles.uitable1,'Data',Data_init0); % this creates an empty table
% to create a table with dropdown
Ndropdown = 4;
dropdown = categorical(ones(Nrows,1),1:Ndropdown,{'Select','HorLayer','VerLayer','Point'});
emp = cell(Nrows,0); % empty cells
tdata = table(dropdown,emp,emp,emp,emp,emp,'VariableNames',{'c1','c2','c3','c4','c5','c6'});
set(handles.uitable1,'Data',tdata);
This gives an error message "Error using matlab.ui.control.Table/set
Functionality not supported with figures created with the figure function. For more information, see Graphics Support in App Designer."
However, this is what I am trying to do:
Ndropdown = 4; Nrows = 40;
dropdown = categorical(ones(Nrows,1),1:Ndropdown,{'Select','HorLayer','VerLayer','Point'});
emp = cell(Nrows,0); % empty cells
tdata = table(dropdown,emp,emp,emp,emp,emp,'VariableNames',{'c1','c2','c3','c4','c5','c6'});
fig0 = uifigure; uit = uitable(fig0,'Data',tdata,'ColumnEditable',true);
I appreciate any ideas to fix the code or if there is any other ideas to do what I am trying to do.

Hi,
Unfortunately, this functionality is not available in GUIDE. You can do the same in App Designer by using this code in the startupFcn callback:
Nrows = 40; Ncols = 6;
Data_init0 = cell(Nrows,Ncols);
app.UITable.Data = Data_init0; % this creates an empty table
% to create a table with dropdown
Ndropdown = 4;
dropdown = categorical(ones(Nrows,1),1:Ndropdown,{'Select','HorLayer','VerLayer','Point'});
emp = cell(Nrows,0); % empty cells
newDisplayData = table(dropdown,emp,emp,emp,emp,emp,'VariableNames',{'c1','c2','c3','c4','c5','c6'});
app.UITable.Data = newDisplayData;
app.UITable.ColumnEditable = true;

Hi,
App Designer and GUIDE are two different methods of creating graphic applications in MATLAB. App Designer provides an enhanced UI component set and design environment. You can know more here.
