how can i read value in the static text in gui?

Answer 1

[TAB]

In your callback function, where you have access to handles structure

StrVal = get(handles.text1,'String');

Anywhere else

th=findobj('Style','text','-and','Tag','text1'); % Find handle of static text
get(th,'String') % Read value

text1 is your static text.

[EDITED] To copy the value of edit text into static text

function edit1_Callback(hObject, eventdata, handles)
str = get(hObject,'String');
set(handles.text1,'String',str);

When you will hit the 'ENTER' key after entering some string in edit text, static text value will also be updated.

[norfaizayu]

how can i read the select word at popup menu list to view at static text?

[Walter Roberson]

function popup1_Callback(hObject, eventdata, handles)

idx = get(hObject, 'Value');

if isempty(idx); return; end

entries = cellstr(get(hObject, 'String'));

thisentry = entries{idx};

set(handles.text1, 'String', thisentry);

if the static text is created from GUIDE, it is impossible to get any callback, ie Text1_Callback(hObject,eventdata,handles) is not valid.

I have tried this:

function Plot1_Info_Callback(hObject, eventdata, handles)

handles=guidata(hObject);

guidata(hObject,handles);

It doesn't work and comes up with en error msg:

"Input argument "hObject" is undefined."

Also, findobj('Style','text') gives an Empty matrix: 0-by-1, although I made two blank static texts in GUIDE.

How can I overcome this?

Cheers!

function DrawSignal(original_data,filtered_data,column_index,column_index2)

global Column_No_UI thickness

subplot(2,1,1);

plot(original_data(column_index,:))

subplot(2,1,2);

plot(filtered_data(column_index2,:))

info_1 = sprintf('Plotted from: | original data | Column# %s | Thicknee %s',num2str(Column_No_UI), num2str(thickness));

set(handles.Plot1_Info,'Spring',info_1)

This is what I did, but I finally get an error msg:

??? Undefined variable "handles" or class "handles.Plot1_Info".

Error in ==> UI_Develop_Test_v1_plot>DrawSignal at 223 set(handles.Plot1_Info,'Spring',info_1)
