Maybe instead of property there can be some protected function like SetAllowDropFiles for these cases. But I think the others want to handle it via OnDragDrop and then you need some enable flag.

On Jan 28, 2008 10:35 PM, Felipe Monteiro de Carvalho [EMAIL PROTECTED] wrote: bump. I think this is a relevant discussion which needs an answer from Tom to progress. Well, we can extend the recent drop files functionality to every TWinControl and change its handling to OnDragDrop, as someone has suggested. We can use some TDragObject descendant, which will hold the list of filenames. There are some things which must be taken into account on various platforms: Windows - there must be some property to enable accepting files, like does AllowDropFiles now - for functional OnDragOver you have to use OLE (IDropTarget) Carbon - there some function to track dropped files on Application level, which is suitable also for other platforms We must also take into account that there can be implemented general drag and drop between App and OS in future.

Re: [lazarus] Carbon TMemo with invisible font
On Nov 18, 2007 8:00 PM, James Chandler Jr [EMAIL PROTECTED] wrote: Hi Tom You do great work! Here is a symptom which might be related (or not). Am only mentioning it because this also had an invisible font issue. Am busy in Win32 right now, and will trace the issue further (if it still exists) when I can get back to carbon in a few weeks. I had four TPaintBoxes in a TPanel, which are graphic views for an audio wave display, a location timestrip, a chord strip, and a piano-roll note strip. Not all paintboxes are erased to the same background color at the start of their OnPaint procs. The drawing in all paintboxes is a mixture of lines, rectangles, and text, of various colors. Some Text drawing used transparent mode, and some did not. This multiple TPaintBox in a TPanel would draw correctly in Win32. On Carbon, it appeared that PaintBox canvas properties were somehow 'leaking' into the parent TPanel canvas, and affecting other TPaintBox OnPaints. The symptom was that some text would draw with the canvas background color (of some other paintbox) rather than the current paintbox Font color. This happened even if I would explicitly set TFont properties before each and every TextOut, in each OnPaint proc. If the background of all the TPaintBoxes had been the same, it would have been completely invisible text. But since the background of the most problematic paintbox was clButtonFace, and some other TPaintBoxes had a clWhite background, I was getting white-on-gray text, rather than the desired black-on-gray text. It may have had something to do with the transparent property leaking between canvases. Dunno. I 'fixed' it on the carbon target, by calling Application.processmessages between each of the TCanvas OnPaint procedures. I think this was flushing the screen after each OnPaint and avoiding transparency or some other property from 'leaking' between canvases. But the gratuitous calling of ProcessMessages slows donw the screen update, so it is just a temporary hack. When I can get back to carbon, will send a bug report with example, if the issue remains. Tobias' reported issue seemed similar, I just thought this example might be related. Here is another 'invisible text' issue-- The default size of Win32 TLabel seems vertically smaller by a pixel or two, than the text rectangle which Carbon likes to draw into. If the TLabel has a default background color and font color, it draws the TLabel correctly in spite of the size discrepancy. In that mode, apparently a TLabel is able to 'overdraw' the control bounds and successfully put un-clipped text onscreen. But for instance if the TLabel Color is black, and the TLabel Font color is green (any non-default color combination would probably show the same bug), then all you get is a black square with no text, if the TLabel is not tall enough to fully contain the text. The fix for that issue was to make the TLabel a few pixels taller than the default size for Win32, and then it draws green on black just fine. That is a minor issue. It may be that carbon refuses to draw any text at all in certain modes, if the destination rectangle isn't tall enough. So there may not be a realistic fix. Perhaps if a fix was attempted, it would involve automatically growing the TLabel (or shrinking the TFont) if the Label is too small to contain the text. It is just that such minor issues take time to diagnose/fix, and makes the thing a little less 'cross platform'. But since carbon likes to draw controls more 'spread out' than Win32, it might be that manual form re-spacing is unavoidable labor when moving code from Win32 to carbon. The minor labor of re-spacing a form is so much less than 'writing from scratch' when moving between platforms. jcjr Hi, sorry that I have found some time for this issue so late.

Re: [lazarus] Thanks Tom Gregorovic re bug 0009952
James Chandler Jr napsal(a): Hi Tom Hi, Thanks for adding the Carbon SetCursorPos patch. Wome feedback on your comment: Thanks. It's only pitty that it does not produce mouse events. I could be mistaken, and appreciate correction, but think that SetCursorPos SHOULD NOT send mouse events (on any platform). That is from my use of SetCursorPos but perhaps there are other uses which would want to generate mouse events. For instance, a favorite control is what I call a TextSlider-- It displays a Text value, and when you click-drag the control, it tracks like a vertical slider, but rather than the text control moving on-screen, the number in the text control just changes in response to vertical mouse movement. This kind of control has been common in music programs since the 1980's. Many round knob controls work similarly. I hilite the textbox and hide the cursor (and pin the hidden cursor on the textbox), or alternately leave the cursor visible and move it to the right of the textbox and 'pin' its location, so that vertical drags cannot move long distances on the screen. If the TextSlider control is near the top of the screen and the user wants to drag the value from 10 to 1000, the value drag would stop when the cursor hits the top of the screen, limiting the amount that the user could drag in a single movement. In that kind usage, it would be undesirable if SetCursorPos would send mouse events. If my OnMouseMove notices that the user dragged up 5 pixels, and then adds 5 to the control's value and updates the screen, and does SetCursorPos to move the cursor back to its original location for further user dragging-- If the control's OnMouseMove SetCursorPos generates a mouse move down event, then that new event would trigger OnMouseMove again, and 'undo' the user's drag, subtracting 5 from the control value and returning the control back to the original value. Haven't traced the code, but am pretty sure that the PC Delphi and PC Lazarus SetCursorPos does not generate mouse move events, otherwise my mouse-tracking controls which use that trick, would never work. Apple strongly disapproves programmatically moving the cursor, and I read somewhere that they supplied the WarpCursorPos function to coddle video game programs, which also need to keep the cursor on-screen for similar reasons that my controls need. It is doubtful that game programmers would want mouse-move events, for the same reasons I don't want em. It could 'undo' the purpose of the SetCursorPos. Sorry for such a boring message. Just wanted to point out that adding a mouse move event to SetCursorPos might be undesirable. Thanks for such great work! That's allright, I comprehend that generating mouse events is sometimes undesirable. I have been following behaviour of SetCursorPos in Lazarus on Windows platform and Delphi (5), where SetCursorPos generates OnMouseMove events. I will add a note on Wiki about this.

If there is anything I can do to help, let me know. Also is there a list somewhere of which Carbon controls have not been ported/wrapped yet? Yes, you can look at http://wiki.lazarus.freepascal.org/Carbon_interface_internals and http://wiki.lazarus.freepascal.org/Roadmap#Status_of_components_on_each_widgetset. Almost all controls are implemented except some printer dialogs. There is more to do in testing and fixing bugs.

Re: [lazarus] Strange Parameter being passed to .app on startup...
Dominique Louis napsal(a): Hi all, The basic conversion is now over, so the debugging begins. When the application is started via the Application Bundle a strange parameter is passed to the executable as the first parameter. The parameter looks like this -psn_0_, where the ns represent some number value that changes every time the application is run. What is this parameter? This application uses the first parameter to load up a data file, so this is throwing things out abit. Any guidance welcome. Hi, I think you can't rely on parameters when you execute app via Application bundle. You can use OnDropFiles event of TApplication or main form, where you can detect files dropped on the app dock icon or to be opened by your app (for example via open -a your.app file). Note that it must be a file. Tom _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Hi, I think over how to implement canvas for Carbon interface. There are two possibilities to use: QuickDraw or Quartz 2D. I want to consult it with you. Here is the list of disadvantages, I have found: QuickDraw - DC of Carbon controls must use Window Port - deprecated in Mac OS X v10.4 Quartz 2D - unable to implement GetPixel, FloodFill, SetPixel must be simulated via line drawing - different coordination system (change Current Transformation Matrix) - bledning instead of ROP - bitmap canvas implementation (needs Mac OS X v10.4 because of CGBitmapContextCreateImage, but we can get round it) Feel free to point out anything I have omitted. From my point of view the Quartz 2D appears to be more suitable, although it doesn't provide per-pixel operations.

The main advantage is direct memory access to bitmap pixels with keeping ability to draw bitmap onto canvas without any widgetset time consuming memory format converting (via StretchDIBits under Win32 and gdk_draw_rgb_32_image under gtk). That's the main reason, why I have developed it. Unfortunately I forgot to mention it on the wiki. Next, the canvas pirmitive drawing is aimed to give the same result across various platforms.

But this is exactly what the TMemoryImage and TImageCanvas do ? Partially yes. But, to draw bitmap form TLazIntfImage (LCL TFPCustomImage wrapper) to widgetset canvas, it must be converted to the TBitmap and that is so slow, especially under gtk.

[lazarus] Patch for Graphics
Hi, this patch moves InvertColor function from SourceEditorProcs to Graphics and adds RGBToColor function, which composes TColor from red, green and blue component like Windows.RGB.
