Win32 Application Icon and Properties

1) Prepare the resource source files in the directory of your program:

File "version_data.rc":

1 VERSIONINFO
FILEVERSION 4,0,3,17
PRODUCTVERSION 3,0,0,0
FILEFLAGSMASK 0
FILEOS 0x40000
FILETYPE 1
{
 BLOCK "StringFileInfo"
 {
  BLOCK "040904E4"
  {
  VALUE "CompanyName","JSC TashkentP"
  VALUE "FileDescription","The main program file"
  VALUE "FileVersion","0.9a"
  VALUE "InternalName","ARM Podpiska"
  VALUE "LegalCopyright","JSC TashkentP’s property"
  VALUE "OriginalFilename","podpiska.pas"
  VALUE "ProductName","The program for ARM Podpiska"
  VALUE "ProductVersion","0.9a"
  }
 }
}

File "icon_data.rc":

 AppIcon ICON "app_icon.ico"

where "app_icon.ico" is 128x128 24bit ICO image. You may use any size at your favour (usually depends on preferable destop resolution/size) commonly greater or equal to 24x24 pixels.

My favorite editor to prepare such (and any kind of image) files is "Embellish".

2) From within Win-32 command shell, compile the prepared files with the supplied FPC resource compiler:

 # windres -O res -i version_data.rc -o version_data.res
 # windres -O res -i icon_data.rc -o icon_data.res

3) use the compiled resources in your application :

program super_puper;

{$ifdef FPC}{$mode objfpc}{$h+}{$INTERFACES CORBA}{$endif}
{$ifdef FPC}
 {$ifdef mswindows}
  {$apptype console}
 {$endif}
{$endif}
uses
 {$ifdef FPC}{$ifdef linux}cthreads,{$endif}{$endif}msegui,mseforms,
 main,dmmain,dmprint, dmacnt1, dmf18,dmrefs,
 connsetupform,mseconsts,mseconsts_ru,mseconsts_uzcyr;

// importing the compiled resources

{$ifdef mswindows}
 {$R version_data.res}
 {$R icon_data.res}
{$endif}

begin
 setlangconsts('ru');
 application.createdatamodule(tdmmainmo,dmmainmo);
 application.createdatamodule(tdmprintmo, dmprintmo);
 application.createdatamodule(tdmacnt1mo, dmacnt1mo);
 application.createdatamodule(tdmf18mo, dmf18mo);
 application.createdatamodule(tdmrefsmo, dmrefsmo);
 application.createform(tmainfo,mainfo);
 application.run;
end.

That's all at the moment.

Dynamic widget creation

To dynamically create a new widget (without using IDE), you need to do the following steps:

• Instantiate a class with its Create constructor (passing the owner as the argument).
• Create a frame for the component and set up its properties.
• Optionally, create a face for the component and set up its properties.
• Set up the component size with bounds_cx and bounds_cy properties.
• Add the component to the window or other container by calling the container's insertwidget.
• Show the component by calling its show method, or by setting visible to true.

Here is an example of dynamically creating a tedit (for this code to work, you need to add dynedit: tedit; property declaration):

procedure tmainfo.mainformcreated(const sender: TObject);
begin
  dynedit := tedit.Create(self);
  dynedit.bounds_cx := 100;
  dynedit.bounds_cy := 21;
  dynedit.createframe;
  dynedit.frame.levelo := -2;
  insertwidget(dynedit, makepoint(300, 10));
  dynedit.show;
end;

If you need custom value for the face property, you can set it up as follows:

  dynedit.createface;
  with dynedit.face do begin
    fade_color.count := 2;
    fade_color[0] := cl_ltgreen;
    fade_color[1] := cl_dkgreen;
    fade_direction := gd_down;
  end;
