Highlight the detail band

rbuser

Hi,

I'd like to highlight the detail band choosed by mouse button, in order
to make it more visible.

The only one line, in each click, choosed by the mouse button.

Could you please guide me how to do that?

Thanks

Hi Ailton,

This is an interesting idea. I just created an article and example
describing how one might go about accomplishing this.

Hi Nico.

I want tell you, how I make this in my app. (and may be you add some of
this in next RB version):

1. My idea: don't put any shapes in report designer. I create special
DrawCommands (TmyBandSelectDrawCommands) in OnCreateDrawCommand event for
all bands from MAIN report. Code for this event is very similar to
CreateBGDrawCommand method.
You can make this internally, like you create BGDrawCommands.

2. TmyBandSelectDrawCommands has next functionality:
a. List of DrawCommands for all internal objects.
b. For DrawCommand classes I register special TDrawCommandModifiers that
change and restore some properties (Brush.Color, Brush.Style,
Gradient.Style, Transparent) of DrawCommands.
TmyBandSelectDrawCommands contains list of this modifiers for DrawCommands
from it List.

3. I add TBandSelectDrawCommandRenders for all devices so that it not
visible in any of them.
As result - selection visible in viewer only (not visible when report
printed on printer or file).

4. I create special modifications of (txt and xls Data) devices, so that
they can print selected bands only. Additionally I used this txt device
for copy text from selected bands in clipboard.

5. I add TmyReportPreviewSelectionController to Previwer. So in any
preview user can save selection to clipboard or save it in file.

6. In my app for detail bands I add additional data (bookmark or Key) in
TmyBandSelectDrawCommands. So I can show popup with context commands for
selected detail bands.
In common case you can add events to TppReport -
OnCreateBandSelectDrawCommand, and GetBandSelectDrawCommandActions as
example.

7. Additionally, I have two kinds of selection - Bands and
TextDrawCommands. In second case I can print and copy in clipboard single
draw commands.
