I want to change a outline view , and add checkbox cell in front of node , and the node have a icon and how to add checkbox in head of the icon?
Download the DragNDropOutlineView sample code from Apple and have a look. It contains all the features you're looking for.
As for adding cells, think of it more in terms of adding columns (a column is designed to hold one cell of a single type). If you want more controls in each row, add a new column and set its cell type. Both of these actions can be performed easily in Interface Builder. You can select the table and increase its column count by one (a new column will appear), move the column where you want it (to the beginning), and drag a checkbox-configured button cell (there's a checkbox cell in the IB palette) into the body of the column and its "data cell" prototype will be set. That's it. Just wire it up as you normally would (NSTableViewDataSource or Cocoa Bindings) and you're done.

is it possible to create listbox with multiple checkboxes in one row (Excel VBA)?
Thanks

I'm not sure I understood your question fully, but I'll elaborate on ListBoxes as much as I can.
First things first: Checkboxes and ListBoxes are different objects in Excel Userforms. The first is the little box that returns a "true/false". The second is a list of items which can be chosen. Clicking in a Checkbox will make the tick mark appear/disappear (or fade if tristate is enabled), while clicking a Listbox row will turn the listbox row "blue"/"white" (or whatever color is being used for the selected rows). In both elements, clicking is a way to toggle between True and False.
While a checkbox only allows for a single information to be marked as True or False, a Listbox allows you to select entries out of a list. That list may be inserted through code (.AddItem method) or passed from a range (.RowSource property)
ListBox objects allow for multiple columns of data to be attributed to one row element, but each row is an entire element (which means you cannot pick the element on row 3, column 2 - only all of row 3). The number of columns is established using the ColumnCount property.
By changing the value of the MultiSelect property, you'll allow the user to select multiple or single row elements simultaneously on your Listbox. Using the Selected( RowIndex ) property, you can check whether or not an item is currently selected (returns True/False). Remember that row indexes start at 0.
Finally, if you're using the MultiSelect property set to fmMultiSelectSingle and have a single column (as far as I know), the Text property can be used to return the selected item's value.
An easy example of a listbox is in Excel can be found at File > Options > Customize Ribbon (or something like that). There are two listboxes, one (on the left) with the visible items and another with the available items. A pair of command buttons is used to move items between boxes. That's a simple application you can likely find already setup online.
Am I on track to answer your question?
I've been Googling for 3 hours, I can't find where to bind these things for Core Data in this textbook I'm reading. I just want to know where to find out where to bind it. I assume it's in the binding inspector after you highlight a column but under value it doesn't show anything like "Col 0 Image View" and for the first column I can't see a section that includes two places to set a binding which needs for an Image View and a Text Field. Below is an excerpt (as well as I can copy it) from the textbook Cocoa Programming for Mac OS X 4th Edition chapter 11, page 185.
"Now bind the value of each column's cell view control(s), as shown in the following table."
One of the entries in the table is:
Binding valueof Col 0 Image View
Bind to Table Cell View
Controller Key Empty
Key Path objectValue.photo
So after a day's work of searching and random clicking I found this rather elusive, yet out-in-the open binding. I hope this helps anyone else who might be frustrated.
This is where to find it, you want to click the one that shows what I have circled. Open the bindings inspector and then it'll pop up with objectValue already populated in your key path.
The first column has two since it has an image view and text view. Make sure to select the appropriate one for whichever one you want bound.
As the title said, can anyone give me a simple example how to get a specific cell's content in wxListCtrl.
For example, I build a wxListCtrl list, there may be 3 columns. When I Right click or Double click on one row, then it should popup a message box to give me the content in third column of this selected row?
Use wxListCtrl::GetItemText() to retrieve the contents of a cell.
I am new to mac app.In my application i have booked history tableview.when the user click on "withdraw" button,I want to strike through the selected row of the tableview.And I am getting tableview content from NSArraycontroller.I don't know how to do it.If any one knows,guide me to do.
This is in mac osx,not in ios.
One way to obtain this would be to use a NSTextView inside your table cell and then bind the attribute string to you array controller. Now in the array controller you can change the relative value by adding an attribute of the type NSStrikethroughStyleAttributeName.
I am trying a simple application where I have a mutable array of mutable dictionaries, such as -
NSMutableDictionary *sample6 = [[NSMutableDictionary alloc] initWithObjectsAndKeys:#"title6",#"title",[NSNumber numberWithBool:NO],#"state", nil];
In IB I created a table view with NSButtonCell (check box).
I was able to show checkboxes state (checked or unchecked), using following table column bindings:
Value - ArrayController.arrangedObjects.state
In this case it shows an array of checkboxes with title - "Check" as shown in below screen-shot:
Now my aim is to show checkboxes title using bindings, such that it
gets value from same mutable dictionary from which it is getting its
state.
I tried following binding for button cell but it did not work:
title -> ArrayController.selection.title
I also tried this binding for button cell :
title -> ArrayController.arrangedObjects.title
but it didn't work, it appeared like this after using above binding:
Can any one suggest me which controller key to use and if this is not the correct way to show titles then what is the correct way to do so?
Unfortunately you'll need to write a little code if you want to do it this way. When binding table column values to an array, the table column is handling taking the prototype data cell, setting its values, and "stamping" it in place for each row. The button cell's bindings aren't exposed "through" the table column, so a simple binding won't do it for you.
To Answer Your Question
So. Since only the value binding is exposed, the title must be set manually if you really want the checkbox's title to reflect the value (ie, you really want the checkbox to handle both the check state and displaying the title). To do this, you have to mix bindings with < NSTableDelegateProtocol > . Use the -tableView:willDisplayCell:forTableColumn:row: method to set the cell's -title property to that of the proper object in your array controller's -arrangedObjects array each time you're asked. Mixing bindings and data source / delegate methods is actually quite common for more than the most basic applications, so don't worry that you're doing something dirty. Note: you won't be able to support editing the title by doing this since it's a checkbox.
An Alternative Design
Personally, I'd avoid all that and just add a separate table column for the title. Bind the new column's value to the array controller's arrangedObjects.title and turn off the checkbox button cell's title so only the checkbox itself is displayed. That simplifies the whole thing greatly and allows editing the title.
