objective c - Problem naming NSTableColumn -

-

I am trying to create a column with an empty string as the identifier but changing the empty string with the word cocoa For every time I try to make the column "field" how can you go around this?

Column with the check box before the {{NSTableView * [[NSTableColumn alloc] initWithIdentifier: @ ""] Equals of Auto;; // checkbox can be started without a title; NSButtonCell * checkbox = [[[NSButtonCell alloc] initTextCell: @ ""] AutoWaves]; [Checkbox set disabled: yes]; [Checkbox setbutton type: NSSwitchButton]; [Checkbox set imaging: nsimaj only]; [Set checkboxTrint size: NSSMLA control-size]; // Add the column with the checkbox for the table [column set datasell: checkbox]; // Add table to column [table addTableColumn: column]; }

Identifier of a column is not the same as its title. You want to set the string value of your-header cell: 

  [[columnColumn headerCell] setStringValue: @ ""];

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
