    <p>Using Firemonkey I have a TVertScrollBox which contains a TPanel which gets dynamically populated with a number of the following TDisplayItem objects.</p> <p>The problem is that the TDisplayItem’s don’t size properly so the text on the various components is superimposed etc. </p> <p>I can fix this on the items that are in the visible area of the scrollbox by by getting the sizes of the component parts and making the containers that size etc. I’ve tried refreshing and application.ProcessMessages to get everything to resize as well as various alignment and warp options but to no avail. </p> <p>Hopefully I’ve missed a key factor in this and haven’t unearthed a Firemonkey limitation!</p> <p>Cheers,</p> <p>Martin.</p> <pre><code>Constructor TDisplayItem.Create(owner : TComponent); begin inherited Create(owner); Align := TAlignLayout.alTop; pnlLabels := TPanel.Create(nil); pnlLabels.Align := TAlignLayout.alTop; pnlLabels.Height := 50; pnlLabels.Parent := self; lblICAO := TLabel.Create(nil); lblICAO.Parent := pnlLabels; with lblICAO do begin text := 'ICAO'; Height := 30; Position.X := 10; align := TAlignLayout.alTop; TextAlign := TTextAlign.taCenter; Font.Size := 18; FontColor := $FF00D000 ; Visible := False; StyledSettings := [TStyledSetting.ssFamily];//, TStyledSetting.ssFontColor]; end; lblFrom := TLabel.Create(nil); lblFrom.Parent := pnlLabels; with lblFrom do begin text := 'From : '; Height := 30; Position.X := 10; Position.y := 2; width := 150; FontColor := $FFFF0000 ; StyledSettings := [TStyledSetting.ssFamily];//, TStyledSetting.ssFontColor]; end; lblTo := TLabel.Create(nil); lblTo.Parent := pnlLabels; with lblTo do begin text := 'To : '; Height := 30; Position.X := 170; Position.y := 2; width := 150; FontColor := $FFFF0000 ; StyledSettings := [TStyledSetting.ssFamily];//, TStyledSetting.ssFontColor]; end; lblStatus := TLabel.Create(nil); lblStatus.Parent := pnlLabels; with lblStatus do begin text := 'Status : '; Height := 30; Position.X := 330; Position.y := 2; width := 100; Font.Size := 10; FontColor := $FFFF0000 ; StyledSettings := [TStyledSetting.ssFamily];//, TStyledSetting.ssFontColor]; end; lblNonGeog := TLabel.Create(nil); with lblNonGeog do begin text := 'Non-Geog : '; Height := 30; Position.X := 440; Position.y := 2; width := 150; Font.Size := 10; FontColor := $FFFF0000 ; StyledSettings := [TStyledSetting.ssFamily];//, TStyledSetting.ssFontColor]; end; lblNonGeog.Parent := pnlLabels; memItem := TLabel.Create(nil); memItem.Parent := self; with memItemE do begin Align := TAlignLayout.alTop; DisableFocusEffect := False; AutoSize := True; WordWrap := True; end; </code></pre>

    1. COAre you setting the size of your TDisplayItems at any point (either in the component or when creating them)? What is the parent of TDisplayItem?

    2. COThe parent is set to be the TPanel that visually contains them. The size is set by iteratively getting the height of each and setting the height of each parent to be the sum of the heights of the child controls.

    3. COSorry, I meant parent class, not parent control. If the class is TPanel, you can make each label a direct child and avoid the extra panel. Then you control height will be the child with the largest Position.Y+Height. I would advise doing this in the display item class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
