I'll have a look at it!

Cheers,

=> recent news are not up-to-date 

Thanks, I'll update it right away. I really should keep a checklist of things to do for each release.

Currently using Delphi7.  I was using Lazarus but the company I work for installed "Digital Guardian Agent" causing application created with Lazarus using windows backin, fail to run.  I can use QT, customdrawn, fpgui widgetset and then the exe runs.

I would prefer to use fpGUI, but it is missing a component I need.  Treeview + ListView.  I currently use VirtualTreeView.

Do you have any plans to create (Treeview + ListView) component?

I saw fpg_nicegrid converted from  delphi.  Could BeniBela's treelistview be convert to fpGUI?

Good job on the new release.  I very much like the new plastic style.  Have not tried win8 style.

Included screen shot of program I want to convert to fpgui.

I'm glad to hear that fpGUI based apps still run! :-) Thank you for trying fpGUI Toolkit.

Do you have any plans to create (Treeview + ListView) component?

To be honest, I'm not a big fan of such composite components. eg: VirtualTreeview - sometimes a treeview, sometimes a listview, sometimes even a grid. TListView has the same issue. I much prefer a widget that dedicates itself to a specific purpose, and does that job very well.

I saw fpg_nicegrid converted from  delphi.  Could BeniBela's treelistview be convert to fpGUI?

I don't know that component, but if past experience taught me anything, it is normally pretty easy and painless to port Delphi/Lazarus components to fpGUI. fpg_nicegrid is just one of many such examples. So I'm sure if you have a little bit of time, you could port that treelistview in no time.

Good job on the new release.  I very much like the new plastic style.  Have not tried win8 style.

Many thanks. Most of the new styles were user contributions. I thought they were so good that I asked if I could include them as official themes. I like those plastic style themes too. As for the Win8 theme - that is something I started and still in the early stages, but should be completed soon.

If you need more detailed information about fpGUI or much quicker support, may I suggest you post fpGUI specific questions in the fpgui.support newsgroup. That way many more fpGUI developers could respond, and future users could learn from all the questions asked and answered.

is there a bitmap type that has 'canvas' property , so that I can draw line, drawrect to it
one more question, I tried 'agg_canvas_test' and it returned SIGSEGV error in"agg_vcgen_stroke.pas" at line 246 'm_width:=w*0.5;'. I also don't understand the line indeed  'ac := TAgg2D(Canvas);'

Hello. Have you enabled the AggPas powered Canvas ?
To do that, edit fpg_main.pas and uncomment the line 25 =>

Code: [Select]

{$define AGGCanvas}
Fred.

[BigChimp]

... or presumably pass

Code: [Select]

-dAGGCanvas
in your project options/other in Lazarus or via your favourite IDE that supports FPC...

Avoids having to edit the source code which may be easier due to git pulls not conflicting etc.

[vkhoa]

Thanks both replies
@BigChimp, I opened that option in Lazarus and the '-dAggCanvas' is already there
@Fred Vs, great! it worked!

[vkhoa]

when enable the AggPas powered canvas, a problem appeared
in other project, the menutest example, at the edit, the caret do not display at the the right position, the figure 1 is showed when the caret at the end, the figure 2 is when selected. And the memo text can't be selected, the button icon  also do not have the transparent effect (does anyone get this problem?)
I mean the error caused by AggPas because when disabling aggpas, the error disapeared
now I can satisfy by enabling and disabling the aggPas when switching project, but in project has both edit memo and aggpas drawing, what can I do

@ vkhoa =>

Could you give a link of this topic (or re-explain it) to fpGUI GitHub issues  =>
https://github.com/graemeg/fpgui/issues

or to fpGUI forum =>
http://opensoft.homeip.net:8080/webnews/

Thanks.

You can use the TAgg2D and call .Attach(bitmap:TfpgImage...). This means you attached a TfpgImage to the Agg2D canvas. Now all TAgg2D drawing routines will paint to the bitmap image.

For documentation on TAgg2D take a look at <fpgui>/docs/aggpas/agg2d.html

[vkhoa]

thanks, I will try it later.

Bravo! I have found the solution for my problem
it is because of the code in fpg_main

Code: [Select]

initialization
{$ifdef AGGCanvas}
  DefaultCanvasClass := TAgg2D;
{$else}
  DefaultCanvasClass := TfpgCanvas;
{$endif} when enable the aggcanvas, it change all the descendant of tfpgwidget's canvas to TAgg2D so that it calculated the text metric wrongly, then I want to have these tfpgwidget's canvas to be tfpgcanvas so I change the fpg_widget unit (or otherwise fpg_base unit), I add a override function to it

Code: [Select]

function    TfpgWidget.CreateCanvas: TfpgCanvasBase;
begin
  result:=TfpgCanvas.create(self);
end;then in my project I create a class

Code: [Select]

type
KfpgWidget =class(TfpgWidget)
  protected
   function    CreateCanvas: TfpgCanvasBase;override;
end;

Code: [Select]

function    KfpgWidget.CreateCanvas: TfpgCanvasBase;
    begin
      result:=TAgg2D.create(self);
    end;now I can use aggpas drawing on my custom widget! )
