• Is there a way to create a python object that will be not sortable?

  - by Graf

  Is there a possibility to create any python object that will be not sortable? So that will be an exception when trying to sort a list of that objects? I created a very simple class, didn't define any comparison methods, but still instances of this class are comparable and thus sortable. Maybe, my class inherits comparison methods from somewhere. But I don't want this behaviour.

• In Python 2.x, using backticks to get decimal string from int object is Horrible?

  - by S.Mark

  In Python 2.x, using backticks to get decimal string from int object is Horrible? Because backticks are repr(), not str()? I have noticed that when I answering this question. In Python source, they have same function in Python source, intobject.c (reprfunc)int_to_decimal_string, /* tp_repr */ .... (reprfunc)int_to_decimal_string, /* tp_str */ What do you think?

• How to override loading a TImage from the object inspector (at run-time)?

  - by Mawg

  Further to my previous question, which did not get a useful answer despite a bounty, I will try rephrasing the question. Basically, when the user clicks the ellipsis in the object inspector, Delphi opens a file/open dialog. I want to replace this handling with my own, so that I can save the image's path. I would have expected that all I need to do is to derive a class from TImage and override the Assign() function, as in the following code. However, when I do the assign function is never called. So, it looks like I need to override something else, but what? unit my_Image; interface uses Classes, ExtCtrls, Jpeg, Graphics; type Tmy_Image = class(Timage) private FPicture : TPicture; protected procedure OnChange(Sender: TObject); public { Public declarations } Constructor Create(AOwner: TComponent); override; procedure SetPicture(picture : TPicture); procedure Assign(Source: TPersistent); override; published { Published declarations - available in the Object Inspector at design-time } property Picture : TPicture read FPicture write SetPicture; end; // of class Tmy_Image() procedure Register; implementation uses Controls, Dialogs; procedure Register; begin RegisterComponents('Standard', [Tmy_Image]); end; Constructor Tmy_Image.Create(AOwner: TComponent); begin inherited; // Call the parent Create method Hint := 'Add an image from a file|Add an image from a file'; // Tooltip | status bar text AutoSize := True; // Control resizes when contents change (new image is loaded) Height := 104; Width := 104; FPicture := TPicture.Create(); self.Picture.Bitmap.LoadFromResourceName(hInstance, 'picture_poperty_bmp'); end; procedure Tmy_Image.OnChange(Sender: TObject); begin Constraints.MaxHeight := Picture.Height; Constraints.MaxWidth := Picture.Width; Self.Height := Picture.Height; Self.Width := Picture.Width; end; procedure Tmy_Image.SetPicture(picture : TPicture); begin MessageDlg('Tmy_Image.SetPicture', mtWarning, [mbOK], 0); // never called end; procedure Tmy_Image.Assign(Source: TPersistent); begin MessageDlg('Tmy_Image.Assign', mtWarning, [mbOK], 0); // never called end; end.

• How can I retrieve the instance of an attribute's associated object?

  - by Brandon Linton

  I'm writing a PropertiesMustMatch validation attribute that can take a string property name as a parameter. I'd like it to find the corresponding property by name on that object and do a basic equality comparison. What's the best way to access this through reflection? Also, I checked out the Validation application block in the Enterprise Library and decided its PropertyComparisonValidator was way too intense for what we need.

• One-liner javascript to collect values from object graph?

  - by Kevin Pauli

  Given the following object graph: { "children": [ { "child": { "pets": [ { "pet": { "name": "fido" } }, { "pet": { "name": "fluffy" } } ] } }, { "child": { "pets": [ { "pet": { "name": "spike" } } ] } } ] } What would be a nice one-liner (or two) to collect the names of my grandchildren's pets? The result should be ["fido", "fluffy", "spike"] I don't want to write custom methods for this... I'm looking for something like the way jQuery works in selecting dom nodes, where you can just give it a CSS-like path and it collects them up for you. I would expect the expression path to look something like "children child pets pet name"

• Can I cache a ManyToOne hibernate object without it being lazy loaded?

  - by Andrew

  @ManyToOne @JoinColumn(name = "play_template_id", table = "team_play_mapping" ) public Play getPlay() { return play; } public void setPlay( Play play ) { this.play = play; } By default, this is eager loading. Can I get it so that it will read the play object from a cache without making it lazy loading? Am I correct that eager loading will force it to do a join query and hence no caching?
