GridCtrl questions [message #31744]

Hello Daniel

A couple of questions about GridCtrl:

- Calling SetToolBar() does not show toolbar automatically until a grid row is selected.
Is there any way to force toolbar to be shown?

- When a row is selected and a Del key or minus button is pushed, is there any Callback that could be called and would confirm or not if row has to be definitively deleted?

Best regards
Iñaki

Hello Sergey

If I put in a button callback SetToolBar() the tool bar does not appear.

Adding to the callback any call to UpdateXXX() or RefreshXXX() functions, it is the same.

The button does appear just when clicking the grid.

1-st in header of TopWindow-class

ToolButton allShipments;
void TEST() {PromptOK("TEST WINDOWS");}
void ShipmentsToolBar(Bar& bar);

2-nd - after initialization (usialy in window constructor)

listbox.SetToolBar();
listbox.WhenToolBar = THISBACK(ShipmentsToolBar);

allShipments.Image(Icons::AllShipments());
allShipments.Label(t_("All shipments"));
allShipments.Text(t_("All Shipments"));
allShipments.Tip(t_("Show All Shipments in single window"));
allShipments.WhenAction = THISBACK(TEST);

3-d - Function to adding additional ToolButton:

void ProjectEditDlg::ShipmentsToolBar(Bar& bar){
    listbox.StdToolBar(bar);
    bar.Separator();
    bar.Add(allShipments);
}

Toolbar (not only in GridCtrl) is visible only if it contains something. Empty toolbar is drawn as a thin line. In GridCtrl you have to activate functions like appending, deleting etc. Try this code for example

grid.Appending().Searching();
grid.SetToolBar();

Yes, there is Smile

WhenRemovedRow (don't confuse with WhenRemoveRow)

Hello Daniel and all

Thank you for your answers.

About Toolbar, the trick is in function RebuildToolBar(). So, the code in callback could be:

grid.Appending(visible).Duplicating(visible).Removing(visible);
grid.RebuildToolBar();

About WhenRemovedRow()... it does not serve as it is a Callback and should be a Gate, I mean, if user clicks Del to remove a row, it would be called to validate or not the deletion so it would have to return some bool.

Any ideas? Smile

Best regards
