I have a popup-menu that has an option, add own material, and when this is chosen, a pushbutton is enabled that say SAVE. I alose have a bunch of edit-boxes.
What I want to do is to make a callback so whenever I click the SAVE, the data from one of the textboxes will possible to select in the popupmenu. when this is selected, I want to set the other edit-boxes to contain the same data that they did when I clicked the save button.
Thanks in advance
I'm not quite sure to fully understand what you want, but you can use the handle of the popup menu to get the string/string array in contains at the time you press the pushbutton. Then you can put those inside the textboxes using their handles as well.
For instance:
MyStrings = get(handlesToYourPopupMenu,'String');
or
MyStringsArray = cellstr(get(handlesToYourPopupMenu,'String'));
which contains the content of the popup menu as a cell array.
and
set(handlesToYourEditBox,'String',MyString);
Is that what you mean? If not please ask :)
EDIT:
To add the new data to the existing content of your text box, use concatenation. Since the content is in a cell array, you can do the following:
NewString = [OldString {CurrentString}];
where CurrentString is obtained with
get(hanlesToYourEditBox,'String');
Therefore to update the content of the popup menu you could write this:
set(handlesToPopUpMenu,'String',[MyStringsArray {get(hanlesToYourEditBox,'String')}]):

I want to get how many strings exist in the popup menu, how can this be done? This code that I have written does not seem to work.
length(get(handles.popupMenu,'Value'))
Value is the index of the currently selected item in the menu so it will only ever be a scalar. You instead want to check the length of the String property which contains a cell array of strings (one for each item).
nOptions = numel(get(handles.popupMenu, 'String'));
I have four items(Types of soils) to be inserted in popup menu and the output should be integer values(porosities) displayed using a static text. How this can be done?
I guess you will be using GUIDE to create your GUI. Here is a simple code for populating a popup menu with pre-defined strings and use the selected item to change the displayed output in the static text:
1) In order to populate the popup menu, simply create a cell array of strings and set the 'String' property of the menu to that cell array:
% Create cell array
SoilTypes = {'Soil A' 'Soil B' 'Soil C' 'Soil D'};
% Set the string property of the popup menu:
set(handles.popupenu1,'String',SoilTypes);
2) Now the callback you are talking about seems to be the Selection Change callback, which might look like this:
function Popupmenu1_SelectionChangeFcn(hObject, eventdata, handles)
This gets executed when the user changes the selected item in the popupmenu. Therefore, you want to get the selected item with this line:
get(handles.popupmenu1,'Value')
So according the the previous cell array, you can use (among other options) a switch/case scenario in which you can do whatever stuff you want for every type of soil, such as displaying text in the static text box. You can also set directly the string in the text box like so:
SelectedItem = get(handles.popupmenu1,'Value') % Get the value, from 1 to 4 in your case
set(handles.text1,'String',SoilTypes{SelectedItem}); % Display the corresponding soil type
Hope that helps get you started!
can somebody please tell me why my pop-up menu list get disappear when I set a string which actually belongs to one of the item in the list? I want this string to be appear as default when GUI gets open, however, want other items to be in the pop-up menu.
For example, pop-up list contains:
Set_1
Set_2
Set_3
Set_4 etc..
And, in the function OpeningFcn, I am settting:
set(handles.popupmenu1, 'String', 'Set_1');
This makes 'Set_1' to appear when I open GUI. However, it makes other items (Set_2, Set_3 etc) disappear from the GUI. Thanks.
The String property of a popupmenu uicontrol sets the entire text that is displayed in the menu.
To select a particular option, set the Value property to the index of the item to be selected. In this case, since Set_1 is the first item, set the Value property to 1.
i have got multi lined text item like gridview in my forms project. i want to select an item and click delete button and the system must delete selected index but i didnt find the perfect function. it's not bind into the database so its not complicated i just want to delete the line from the text item. i tried to find the properties of the current record, i use some of loops but it didnt find the selected item index. does it have "selected item" function like c#, java. Or do i have to create a function to find selected item. which way is the best and how could i do that.
This code may help you(I didn't get a chance to test this) :
GO_BLOCK('Gridview_BLOCK_NAME');
GO_RECORD(record_index);
DELETE_RECORD;
GO_ITEM('block.delete_button');--if you want the cursor back to delete button
I have a listbox ,which have two values value1 and value 2 ..
Now my listbox values got change programatically (I dont change the values Manually)
I want to get a prompt prompt whenever a value get changes / index get changed, inside my listbox
ListBox listBox = new LisBox();
if i use
listBox.addClickHandler
or
listBox.addChangeListener
or
listBox.addChangeEvent
They all only shows me a prompt when i manually change my listbox selected Index.But how will i get a prompt when my listbox selectedIndex changed programatically
Thanks
I am assuming that you are using
setSelectedIndex
The javadoc says explicitly states that it will not send an event. You could overwrite setSelectedIndex and send your own event. A good explaination of doing so can be found here.
