MATLAB: Cycle trough handles on GUI

cycleguidehandles

Dear all, this is probably a stupid question and it was probably asked a thousand times before… Anyway… I have a GUI with a lot of tables. Every table's content is held by a handle called handle.table1, handle.table2 and so forth.

I would like to be able to change the content of the tables automatically with a for cycle.

So far I'm doing this: set(handle.table1, 'PropertyName', PropertyValue) set(handle.table3, 'PropertyName', PropertyValue) set(handle.table2, 'PropertyName', PropertyValue)

And I would like to do this:

for N=1:20

set(handle.tableN, 'PropertyName', PropertyValue)

end

But… how can I do it? I would like not to change the structure of the handle as that would be a messy solution since I have 4000 lines of code and would require a big rework of the whole GUI…

Thanks a lot!

Lorenzo

That's great, thanks! I guess I'll ty and use eval in order to do that… That's something I've already done in the past but I wasn't sure if I could do that with handles as well…

MATLAB: How to read the value of the inputs of a block during runtime

gcb is the current block. So if you need a Value of the Propert 'PropertyName', of the current block, you should do

rto = get_param(gcb, 'PropertyName');

You should have selected the inport block so that gcb points that block. In other words, make that inport as the current block by clicking on it.

If you do not want to click on the block, but know the blocks name, then you can do

rto = get_param(BlockPath, 'PropertyName');

And to know the all the properties of the current block, click on the block(set it as current block), then in command window, type

get(gcbh)

gcbh is the handle of the current block, get(gcbh) will list all the properties and values of the current block.

MATLAB: Do I get the error message ‘There is no ‹PropertyName› property in the ‹ClassName› class.’

Explanation:

You are attempting to set a property of a graphics object, but that property is not a property of that object. Alternatively, that name does not correspond to a property of that class.

Common causes:

You are attempting to set a property of a graphics object, such as FontName or Callback for a figure, but figure objects have neither a FontName nor a Callback property. If you know that the object has that property, there may be a typographical error in the name of the property.

Solution:

Verify that the name in the SET or GET statement on the line listed in the error message is spelled correctly and that the property you are attempting to access with the SET or GET function is a valid property for that type of Handle Graphics object using the Handle Graphics Object Properties browser.

Example demonstrating this error:

InvalidObjectProperty.m
