I have the following way, to make edits invisible.
edt_raster5.visible := false;
edt_raster6.visible := false;
edt_raster7.visible := false;
edt_raster8.visible := false;
edt_raster9.visible := false;
Is there a way to use a loop to make it easier? I know it's very simple but I'm not getting it right ... I tried the following but it clearly did not work out.
for i := 1 to 9
edt_raster[i].visible := false;
You can scan the Components property of your Form where all its components are stored and see which are Edit to change.
Example:
for I := 0 to Form1.ComponentCount - 1 do
begin
if Form1.Components[I] is TEdit then
TEdit(Form1.Components[i]).Visible = false;
end;
for i := 1 to 9 do
begin
TEdit(FindComponent('edt_variavel'+IntToStr(i))).Visible := false;
end;
Resolved my issue.
I usually work this way
for i := 0 to ComponentCount - 1 do // percore todos os componentes do form
begin
if Components[I] is TEdit then // se for TEdit
begin
if (TEdit(Components[i]).name = 'edtDescricao') then // se o componente for igual ao nome
TEdit(Components[i]).visible := True
else
TEdit(Components[i]).visible := False;
end;
end;
