I want to change the table view column header text on double clicking column header.
For that I created a subclass of NSTableHeaderCell like-
#interface NBETableHeaderCell : NSTableHeaderCell<NSTextFieldDelegate,NSTableViewDelegate>
#end
#import "NBETableHeaderCell.h"
#implementation NBETableHeaderCell
- (void)textDidEndEditing:(NSNotification *)notification
{
NSTextView *editor = notification.object;
[self setTitle:editor.string];
[self setHighlighted:NO];
[self endEditing:editor];
}
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView
{
if([self isHighlighted])
{
[self drawFocusRingMaskWithFrame:cellFrame inView:controlView.superview];
}
[super drawWithFrame:cellFrame inView:controlView];
}
- (void)drawFocusRingMaskWithFrame:(NSRect)cellFrame inView:(NSView *)controlView
{
[controlView lockFocus];
NSSetFocusRingStyle(NSFocusRingOnly);
[[NSBezierPath bezierPathWithRect:cellFrame] fill];
[controlView unlockFocus];
}
#end
I set the table column header cell class
-(void)setupTableHeader:(id)table {
NSArray *columns = [table tableColumns];
NSEnumerator *cols = [columns objectEnumerator];
NSTableColumn *col = nil;
NBETableHeaderCell *iHeaderCell;
while (col = [cols nextObject]) {
iHeaderCell = [[NBETableHeaderCell alloc] initTextCell:[[col headerCell] stringValue]];
[col setHeaderCell:iHeaderCell];
[[col headerCell] setEditable:YES];
[iHeaderCell release];
}
[table setTarget:self];
[table setDoubleAction:#selector(doubleClickInTableView:)];
}
The double click action I set was :
- (void)doubleClickInTableView:(id)sender
{
NSInteger row = [myTableView clickedRow];
NSInteger column = [myTableView clickedColumn];
if(row == -1&& column >= 0)
{
NSTableColumn *tableColumn = [[myTableView tableColumns] objectAtIndex:column];
NSTableHeaderView *headerView = [myTableView headerView];
NBETableHeaderCell *headerCell = [tableColumn headerCell];
id cellEditor = [self.view.window fieldEditor:YES forObject:myTableView];
[headerCell setHighlighted:YES];
[headerCell selectWithFrame:[headerView headerRectOfColumn:column]
inView:headerView
editor:cellEditor
delegate:headerCell
start:0
length:headerCell.stringValue.length];
[cellEditor setDrawsBackground:YES];
}
}
Now, I am able to edit the column header and set a new text. On tabbing out the new text persist. But if I set a new text and instead of tabbing out I click on other table column header, my text is not changed, the old value is being retained. This may be because the delegate - (void)textDidEndEditing:(NSNotification *)notification is not called upon selecting other table column header. This delegate is only called on tabbing out. Please suggest, how can set the new value in the table column header cell without tabbing out?

How do I generate indentation marker for NSOutlineView?
I am not sure if this is an inbuilt functionality because it appears in other apps like Instruments
Update
I tried solving the problem by iterating all the children of the item that the row represents and show the marker on all children rows based on indentation level, but I faced a few problems
How to handle the case where the item has thousands of children. One simply cannot draw marker to every row as NSOutlineView would draw rows as they are displayed
When I scroll the NSOutlineView, the mouse moves out of the specified row but mouseExited is not being called. Thus the user has to manually move the mouse to reload the highlighting.
I had solved this problem but my solution looks hacky hence wanted to know if there is a better solution. And hence the question
First to receive mouseEntered: and mouseExited: events you need to setup a tracking rect using NSTrackingArea.
I would start with a subclass of NSTableRowView thats overwrites setFrame: making sure the tracking rect gets updated when the view is resize:
#interface TableRowView : NSTableRowView {
NSBox *_box;
NSTrackingArea *_trackingArea;
}
#property (weak) id owner;
#property (copy) NSDictionary<id, id> *userInfo;
#property (nonatomic) CGFloat indentation;
#property (nonatomic) BOOL indentationMarkerHidden;
#end
#implementation TableRowView
- (void)setFrame:(NSRect)frame
{
[super setFrame:frame];
if (_trackingArea) {
[self removeTrackingArea:_trackingArea];
}
_trackingArea = [[NSTrackingArea alloc] initWithRect:[self bounds] options:NSTrackingMouseEnteredAndExited|NSTrackingActiveInKeyWindow owner:[self owner] userInfo:[self userInfo]];
[self addTrackingArea:_trackingArea];
}
#end
To use the NSTableRowView subclass, implement the NSOutlineViewDelegate messages like this:
- (NSTableRowView *)outlineView:(NSOutlineView *)outlineView rowViewForItem:(id)item
{
TableRowView *view = [[TableRowView alloc] init];
view.owner = self;
view.userInfo = item;
return view;
}
With this in place you're ready to receive mouseEntered: and mouseExited: events. Use NSOutlineView levelForItem: together with indentationPerLevel to calculate the position of the marker NSBox.:
- (void)mouseEntered:(NSEvent *)event
{
id item = [event userData];
CGFloat indentation = [_outlineView levelForItem:item] * [_outlineView indentationPerLevel];
[self setIndentationMarker:indentation hidden:NO item:item];
}
- (void)mouseExited:(NSEvent *)event
{
id item = [event userData];
[self setIndentationMarker:0.0 hidden:YES item:item];
}
Now you get the NSTableRowView subclass by rowViewAtRow:makeIfNecessary: and recursively do the same for all children in your data:
- (void)setIndentationMarker:(CGFloat)indentation hidden:(BOOL)hidden item:(NSDictionary *)item
{
TableRowView *view = [_outlineView rowViewAtRow:[_outlineView rowForItem:item] makeIfNecessary:NO];
view.indentationMarkerHidden = hidden;
view.indentation = indentation;
for (NSMutableDictionary *child in [item objectForKey:#"children"]) {
[self setIndentationMarker:indentation hidden:hidden item:child];
}
}
Now layout the NSBox the NSTableRowView subclass:
#implementation TableRowView
- (instancetype)init
{
self = [super init];
if (self) {
_indentationMarkerHidden = YES;
_box = [[NSBox alloc] init];
_box.boxType = NSBoxCustom;
_box.borderWidth = 0.0;
_box.fillColor = [NSColor tertiaryLabelColor];
_box.hidden = _indentationMarkerHidden;
[self addSubview:_box];
}
return self;
}
- (void)layout
{
[super layout];
NSRect rect = [self bounds];
rect.origin.x = _indentation + 7;
rect.size.width = 10;
_box.frame = rect;
}
- (void)setIndentation:(CGFloat)indentation
{
_indentation = indentation;
[self setNeedsLayout:YES];
}
- (void)setIndentationMarkerHidden:(BOOL)indentationMarkerHidden
{
if (_indentationMarkerHidden != indentationMarkerHidden) {
_indentationMarkerHidden = indentationMarkerHidden;
_box.hidden = indentationMarkerHidden;
}
}
#end
This enough to make a basic version like here:
I have a cocoa app with a window containing an NSTableView. Each row has a few columns, three radio boxes and two buttons. Currently the table has 260 rows and when the window is focused the scrolling in the table view is atrociously slow and jittery. When the window is not focused and I mouse over the table view and scroll it's buttery smooth.
I've tried to solve the slow performance by changing the background drawing and enabling CoreAnimation Layer to no avail.
Why would the scrolling be fast when the window isn't focused but slow when it is?
I'm just baffled as to why the scrolling is so darn slow.

There's also code that establishes the SqLite DB connection and interacts with the DB to get the records or delete etc... but that's not really needed here... I also have code that draws the radio buttons and the other buttons but again, I don't think that's necessary unless someone thinks that the drawing is creating the slowdown...?
So it turns out that the drawing of the radio buttons is what is causing the slowdown... back to the drawing board.
I am not really familiar with tables, as I usually make games, but now I want to create a level builder where I need a table view with custom cells. I have created a nib file and I have subclassed NSTableCellView, but I don't know what to do next. All I have is:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification{
NSScrollView * tableContainer = [[NSScrollView alloc] initWithFrame:NSMakeRect(self.window.frame.size.width-TABLEWIDTH, 0, TABLEWIDTH, self.window.frame.size.height)];
SpriteTable *sT = [[SpriteTable alloc]initWithFrame:NSMakeRect(self.window.frame.size.width-TABLEWIDTH, 0, TABLEWIDTH, self.window.frame.size.height)];
NSTableView *tableView = [[NSTableView alloc] initWithFrame: sT.bounds];
NSTableColumn* firstColumn = [[[NSTableColumn alloc] initWithIdentifier:#"firstColumn"] autorelease];
[[firstColumn headerCell] setStringValue:#"First Column"];
[tableView addTableColumn:firstColumn];
tableView.dataSource = self;
tableView.delegate = self;
[tableContainer setDocumentView:tableView];
tableContainer.autoresizingMask = NSViewHeightSizable | NSViewMinXMargin;
[self.window.contentView addSubview: tableContainer];
}
- (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView{
return 4;
}
- (NSView *)tableView:(NSTableView *)tableView
viewForTableColumn:(NSTableColumn *)tableColumn
row:(NSInteger)row {
// get an existing cell with the MyView identifier if it exists
CustomCell *result = [tableView makeViewWithIdentifier:#"MyView" owner:self];
// There is no existing cell to reuse so we will create a new one
if (result == nil) {
NSLog(#"result = nil");
// create the new NSTextField with a frame of the {0,0} with the width of the table
// note that the height of the frame is not really relevant, the row-height will modify the height
// the new text field is then returned as an autoreleased object
//result = [[[NSTextField alloc] initWithFrame:NSMakeRect(0, 0, 250, 70)] autorelease];
// the identifier of the NSTextField instance is set to MyView. This
// allows it to be re-used
result.identifier = #"MyView";
}
// result is now guaranteed to be valid, either as a re-used cell
// or as a new cell, so set the stringValue of the cell to the
// nameArray value at row
result.imageView.image = [NSImage imageNamed:NSImageNameHomeTemplate];
// return the result.
return result;
}
If any, which delegate methods do I have to implement ? And how do I customize my cell WITH a nib file ?
Do this in ur subview->
#implementation suhasView
#synthesize name,containerView;// container view contains ur subview
- (NSView*) myView
{
NSBundle *bundle = [NSBundle bundleForClass:[self class]];
NSNib *theNib = [[NSNib alloc] initWithNibNamed:#"suhas"bundle:bundle];
[theNib instantiateNibWithOwner:self topLevelObjects:nil];
return containerView;
}
In Controller->
- (NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
{
suhas *a=[[suhas alloc]initWithFrame:NSMakeRect(0,0, 40, 40)];
NSView * v = [a myView];
[a.name setStringValue:#"suhas"];
return v;
}...//sorry for my naming of the class:)

I know this is super old and the video is removed so I am not sure what the exact problem is but it is most certainly related to you instantiating everything in our viewDidUnload... You should be doing this in your viewDidLoad most likely.
I try to make bold row selection style in NSTableView without any highlighting
I switched highlighting off:
[myTable setSelectionHighlightStyle:NSTableViewSelectionHighlightStyleNone];
However I have some troubles making text bold in selected row. As I suggested, I need to change properties of NSTableView's source:
- (void) tableViewSelectionDidChange: (NSNotification *) notification
{
NSDictionary *boldFont = [NSDictionary dictionaryWithObject:[NSFont boldSystemFontOfSize:13.0]
forKey:NSFontAttributeName];
NSDictionary *normalFont = [NSDictionary dictionaryWithObject:[NSFont systemFontOfSize:13.0]
forKey:NSFontAttributeName];
for(MyClass *obj in tableSourceList)
obj.name = [[NSMutableAttributedString alloc]
initWithString:obj.name
attributes: normalFont];
long row = [myTable selectedRow];
MyClass objectAtSelectedRow = [tableSourceList objectAtIndex: row];
objectAtSelectedRow.name = [[NSMutableAttributedString alloc]
initWithString:dr.dreamname
attributes: boldFont];
[tableSourceList replaceObjectAtIndex:row withObject:objectAtSelectedRow];
}
Unfortunately, there's no effect.
How to make text in row bold when selected?
You can try to achieve by altering the table cell to be rendered in the table's delegate:
- (void)tableView:(NSTableView *)aTableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex {
// Maybe a test on the table column is recommanded if some cells should not be modified
NSIndexSet *selection = [aTableView selectedRowIndexes];
if ([selection containsIndex:rowIndex]) {
[aCell setFont:[NSFont boldSystemFontOfSize:12]];
} else {
[aCell setFont:[NSFont systemFontOfSize:12]];
}
}
