MATLAB: What is edit text box type in GUI when I using findobj function

findobjgui

Hi,

I try to get GUI edit text box object in separate m-file because I like to print something to this text box from m-file. What is the 'Type' of this edit text box when using findobj function?

Hello Teemu,

I understand that you would like to use the findobj function to get access to edit boxes in a GUI.

The 'Type' of an edit box is actually 'uicontrol', just like all other UI Controls (push buttons, pop-up menus, etc). However, you can specify the 'Style' property when calling findobj to get only edit boxes:

figure
uicontrol('Style','pushbutton')
uicontrol('Style','edit')
hEditBoxes = findobj('Type','uicontrol','Style','edit');

Note that if you use findobj a lot in your code, it can slow things down. If at all possible, save the handle from when you create the edit box (or extract it from the handles structure if the GUI is made in GUIDE) and pass it as an input argument to the function that needs access to the edit box.

I hope that this has helped!

MATLAB: Findobj does not work

Either there is no object with exactly that name, or else the handle of it is not visible.

What shows up for

get(findall('type', 'figure'), 'Name')

MATLAB: Findobj for multiple ‘Tag’s

When you use findobj, it returns the object handle (May look like an arbitrary number to the user). There are many ways to do what you want I think. Here is one

First, create a cell array with the names of the tags you want to find, then use findobj in a loop to collect the object handles.

mytags = {'Name1' 'Name2' 'Name3' ... )
for i = length(mytags)
     objecthandles.(genvarname(mytags{1})= findobj(0, 'tag', mytags{1})
end

The output should be a structure of variables called 'objecthandles' that has variables for each of your tag names, and the variables store the object handles.

The output should look something like:

objecthandles = 
   objecthandles.Name1 = 300.12
   objecthandles.Name2 = 292.73
   objecthandles.Name3 = 512.42
   ...

You now are able to call all of their handles at will. Let me know if I made a syntax error or soemthing and I can correct this.
