TSMBIOS now supports Linux via Delphi 10.2 Tokyo.
I just uploaded a new version of the TSMBIOS library with support for Linux via Delphi 10.2 Tokyo. You can found a full description of the project in the Github site.
Check these screenshots of the demo applications running under ubuntu 16.04 LTS
Now just a small note, the TSMBIOS library access to the SMBIOS data reading the /dev/mem device file (which provides direct access to system physical memory). So the applications which uses this library require being executed by an user with access to such file, typically a superuser.

TListView OwnerDraw compat with Windows UI & VCL Styles
There is a lot of resources of how ownerdraw a Delphi TListView, but most of them are deprecated and don’t take into account the VCL Styles and the StyleServices.
So on this post I will show you how you can ownerdraw a TListView to be compatible with the native Windows Look and feel and the VCL Styles.
First, there is lot of ways to ownerdraw a TListView , but on this post we will focus only in the OnDrawItem event, because offers more flexibility than the OnCustomDrawXXX events handlers .
The OnDrawItem is an event handler of type Vcl.ComCtrls.TLVDrawItemEvent
This is the definition of such event
TLVDrawItemEvent = procedure(Sender: TCustomListView; Item: TListItem; Rect: TRect; State: TOwnerDrawState) of object;
Parameters
- Sender : The ListView which is raising the event.
- Item : The list item which need to be drawn. (you can use this object to read the data of the ListView).
- Rect : The bounds of the item (including the subitems).
- State : The current state of item.
Note: Before to use the OnDrawItem event you must set the value of the property TListView.ownerdraw to True.
Ok, So I’m planning create a TListview in report mode and draw some controls like a checkbox and progressbar. These controls must looks perfect under the Windows UI and the VCL Styles.
I will start creating the columns of the TListview in runtime (just for personal preference.). I’m using a TDictionary to hold the columns reference in that way I prevent create one variable per column and also I can access the columns by a Name.
procedure TFrmMain.AddColumns;
Procedure AddColumn(const AColumnName : String; AWidth : Integer; AColumnType : TColumnType);
begin
FColumns.Add(AColumnName, LvSampleData.Columns.Add());
FColumns[AColumnName].Caption := AColumnName;
FColumns[AColumnName].Width := AWidth;
FColumns[AColumnName].Tag := Integer(AColumnType);
end;
begin
FColumns := TDictionary<string, TListColumn>.Create();
AddColumn('Text', 150, ctText);
AddColumn('Porc', 100, ctProgress);
AddColumn('Text2', 150, ctText);
AddColumn('Enabled', 100, ctCheck);
end;
Please pay attention to the Tag property of the Columns, I’m using this to store the type of the column (TColumnType is a custom type).
TColumnType = (ctText, ctCheck, ctProgress);
Next we need fill the listview with some sample data (This doesn’t requires much explanation right?).
const
MaxItems = 100;
var
LItem : TListItem;
i : Integer;
begin
Randomize;
LvSampleData.Items.BeginUpdate;
try
for i := 0 to MaxItems - 1 do
begin
LItem := LvSampleData.Items.Add;
LItem.Caption:= Format('Sample text', []);
LItem.SubItems.Add(IntToStr(Random(101)));
LItem.SubItems.Add(Format('Sample text 2', []));
LItem.SubItems.Add(IntToStr(Random(2)));
end;
finally
LvSampleData.Items.EndUpdate;
end;
end;
And now I can start to draw the TListView items using the the OnDrawItem event.
First I will store a reference to the StyleServices function (In this way I’m avoiding call the same function again and again).
Note : The StyleServices method returns an instance of a TCustomStyleServices type, which allow to gain access to all the styling functionality of the current active style (Windows or VCL Style).
Next I will erase any previous content of the current row by filling with the current clWindow color.
Check how the clWindow const is used in the TCustomStyleServices.GetSystemColor function to return the current Window Background color.
procedure TFrmMain.LvSampleDataDrawItem(Sender: TCustomListView; Item: TListItem; Rect: TRect; State: TOwnerDrawState); ... ... begin LStyleService := StyleServices; if not LStyleService.Enabled then exit; Sender.Canvas.Brush.Style := bsSolid; Sender.Canvas.Brush.Color := LStyleService.GetSystemColor(clWindow); Sender.Canvas.FillRect(Rect); LRect := Rect;
Now I will iterate over all the columns of the Listview resolving the current column type, the text stored in the current item and calculating the bounds of the current item.
...
...
for i := 0 to TListView(Sender).Columns.Count - 1 do
begin
LColummnType := TColumnType(TListView(Sender).Columns[i].Tag);
LRect.Right := LRect.Left + Sender.Column[i].Width;
LText := '';
if i = 0 then
LText := Item.Caption
else
if (i - 1) <= Item.SubItems.Count - 1 then
LText := Item.SubItems[i - 1];
....
....
Note : The OnDrawItem event is raised once per each row of the ListView, So you must draw all the items and subitems yourself).
Now depending of the column type (Text, CheckBox or ProgressBar) I will draw the item.
Text
For the columns of type text (ctText), I check if the State of the item is Selected or Hot and Draw the highlight bar (using the TCustomStyleServices.DrawElement method) and finally the text is rendered using the TCustomStyleServices.DrawText function.
Check how the color of the text is selected depending of the state of the item.
ctText: begin
LDetails := LStyleService.GetElementDetails(tgCellNormal);
LColor := LStyleService.GetSystemColor(clWindowText);
if ([odSelected, odHotLight] * State <> []) then
begin
LDetails := LStyleService.GetElementDetails(tgCellSelected);
LColor := LStyleService.GetSystemColor(clHighlightText);
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect);
end;
LRect2 := LRect;
LRect2.Left := LRect2.Left + ListView_Padding;
LTextFormat := TTextFormatFlags(DT_SINGLELINE or DT_VCENTER or DT_LEFT or DT_END_ELLIPSIS);
LStyleService.DrawText(Sender.Canvas.Handle, LDetails, LText, LRect2, LTextFormat, LColor);
end;
CheckBox
For the checkbox columns, the process start in the same way, first check if the item is highlighted and then the bar is drawn.
Then I calculate the bounds of the checkbox and get the text for the column. (for this sample the Value 1 means checked otherwise means unchecked).
Now according to the value and the state of the checkbox is draw.
Please pay attention to how the the element to be drawn is selected depending of the current state and the current text.
ctCheck: begin
if ([odSelected, odHotLight] * State <> []) then
begin
LDetails := LStyleService.GetElementDetails(tgCellSelected);
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect);
end;
LSize.cx := GetSystemMetrics(SM_CXMENUCHECK);
LSize.cy := GetSystemMetrics(SM_CYMENUCHECK);
LRect2.Top := Rect.Top + (Rect.Bottom - Rect.Top - LSize.cy) div 2;
LRect2.Bottom := LRect2.Top + LSize.cy;
LRect2.Left := LRect.Left + ((LRect.Width - LSize.cx) div 2);
LRect2.Right := LRect2.Left + LSize.cx;
if (LText = '1') then
begin
if ([odSelected, odHotLight] * State <> []) then
LDetails := LStyleService.GetElementDetails(tbCheckBoxCheckedHot)
else
LDetails := LStyleService.GetElementDetails(tbCheckBoxCheckedNormal);
end
else
begin
if ([odSelected, odHotLight] * State <> []) then
LDetails := LStyleService.GetElementDetails(tbCheckBoxUncheckedHot)
else
LDetails := LStyleService.GetElementDetails(tbCheckBoxUncheckedNormal);
end;
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect2);
end;
ProgressBar
Finally for the progressbar columns, after of check the current state I draw the frame of the progress bar by using the tpBar element, then getting the current value for the column I calculate the bounds of the chunks to be draw. Then depending of the value I fill the progress bar with a solid color or with the element of the current style.
ctProgress:
begin
if ([odSelected, odHotLight] * State <> []) then
begin
LDetails := LStyleService.GetElementDetails(tgCellSelected);
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect);
end;
LRect2 := ResizeRect(LRect, 2, 2, 2, 2);
LDetails := LStyleService.GetElementDetails(tpBar);
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect2);
if not TryStrToInt(LText, p) then p := 0;
InflateRect(LRect2, -1, -1);
LRect2.Right := LRect2.Left + Round(LRect2.Width * p / 100);
if p < 20 then
begin
Sender.Canvas.Brush.Style := bsSolid;
Sender.Canvas.Brush.Color := clWebFirebrick;
Sender.Canvas.FillRect(LRect2);
end
else
if p < 50 then
begin
Sender.Canvas.Brush.Style := bsSolid;
Sender.Canvas.Brush.Color := clWebGold;
Sender.Canvas.FillRect(LRect2);
end
else
begin
LDetails := LStyleService.GetElementDetails(tpChunk);
LStyleService.DrawElement(Sender.Canvas.Handle, LDetails, LRect2);
end;
end;
This is the final result of the code
As you can see the list view is draw consistently under Windows or when a custom Style is used.
