Chris Holland SEC Solutions Ltd. Team Elevate | Hi Tim,
Sorry for the delay, been on an extended holiday I used the code that Mark posted and changed my TComponent to a TControl and set the parent to nil and then the error went away. When I created the panels in the first place I didn't do it the way you showed in your code: TBasicPanel.Create(Self); Because they were placed on another top level panel they were created using this: TempPanel := TBasicPanel.Create(JobListSubPanel); TempPanel.Layout.Position := lpTopLeft; TempPanel.Layout.Consumption := lcBottom; TempPanel.Layout.Reset := true; TempPanel.Layout.Stretch := lsRight; TempPanel.Width := PanelWidth; TempPanel.Height := 100; TempPanel.Tag := PanelCount; TempPanel.Name := 'AppointmentPanel' + IntToStr(PanelCount); TempPanel.OnClick := AppointmentPanelClicked; TempPanel.Border.Top.Visible := true; TempPanel.Border.Bottom.Visible := true; TempPanel.Border.Left.Visible := true; TempPanel.Border.Right.Visible := true; TempPanel.Background.Fill.FillType := ftSolid; TempPanel.Background.Fill.Color := clCornSilk; if Appointment.StartDate < Now then TempPanel.Background.Fill.Color := clPink; Hope this helps. (Although it is all working fine now with those changes) Chris Holland [Team Elevate] |

Mark Brooks Slikware | Hi Chris
I have also seen "strange" behaviour if I didn't set the Parent to nil, but that was some time ago and maybe has been fixed / enhanced now. Hence my question about whether I need to or not. Cheers Mark |

<< Sorry for the delay, been on an extended holiday >> I hope you had a great time. I tried this again with no ill effects, and this is the code that I'm using: // Creation procedure TForm1.Button1Click(Sender: TObject); var I: Integer; TempPanel: TBasicPanel; begin for I:=0 to 4 do begin TempPanel := TBasicPanel.Create(BasicPanel1); TempPanel.Layout.Position := lpTopLeft; TempPanel.Layout.Consumption := lcBottom; TempPanel.Layout.Reset := true; TempPanel.Layout.Stretch := lsRight; TempPanel.Width := BasicPanel1.ClientWidth; TempPanel.Height := 100; TempPanel.Tag := I; TempPanel.Name := 'AppointmentPanel' + IntToStr(I); // TempPanel.OnClick := AppointmentPanelClicked; TempPanel.Border.Top.Visible := true; TempPanel.Border.Bottom.Visible := true; TempPanel.Border.Left.Visible := true; TempPanel.Border.Right.Visible := true; TempPanel.Background.Fill.FillType := ftSolid; TempPanel.Background.Fill.Color := clCornSilk; end; end; // Removal procedure TForm1.Button2Click(Sender: TObject); var i: Integer; c: TComponent; begin for i := BasicPanel1.ControlCount - 1 downto 0 do begin c := BasicPanel1.Controls[i]; if c is TBasicPanel then begin c.Free; end; end; end; Could you possibly try the code there and see if you're still seeing any issues with closing the form/deleting the panels ?

Chris Holland SEC Solutions Ltd. Team Elevate | Hi Tim,
That all appears to work fine. I can't test the original code as having been on holiday I can't remember which part of my code I was having problems with as I found a solution so didn't keep a not of it Chris Holland [Team Elevate] On 03/07/2017 19:04, Tim Young [Elevate Software] wrote: > Chris, > > << Sorry for the delay, been on an extended holiday >> > > I hope you had a great time. > > I tried this again with no ill effects, and this is the code that I'm using: > > // Creation > > procedure TForm1.Button1Click(Sender: TObject); > var > I: Integer; > TempPanel: TBasicPanel; > begin > for I:=0 to 4 do > begin > TempPanel := TBasicPanel.Create(BasicPanel1); > TempPanel.Layout.Position := lpTopLeft; > TempPanel.Layout.Consumption := lcBottom; > TempPanel.Layout.Reset := true; > TempPanel.Layout.Stretch := lsRight; > > TempPanel.Width := BasicPanel1.ClientWidth; > TempPanel.Height := 100; > TempPanel.Tag := I; > TempPanel.Name := 'AppointmentPanel' + IntToStr(I); > // TempPanel.OnClick := AppointmentPanelClicked; > > TempPanel.Border.Top.Visible := true; > TempPanel.Border.Bottom.Visible := true; > TempPanel.Border.Left.Visible := true; > TempPanel.Border.Right.Visible := true; > > TempPanel.Background.Fill.FillType := ftSolid; > TempPanel.Background.Fill.Color := clCornSilk; > end; > end; > > // Removal > > procedure TForm1.Button2Click(Sender: TObject); > var > i: Integer; > c: TComponent; > begin > for i := BasicPanel1.ControlCount - 1 downto 0 do > begin > c := BasicPanel1.Controls[i]; > if c is TBasicPanel then > begin > c.Free; > end; > end; > end; > > Could you possibly try the code there and see if you're still seeing any issues with closing the form/deleting the panels ? > > Thanks, > > Tim Young > Elevate Software > www.elevatesoft.com > |
