How to use the Function Sender Object |
Fri, Mar 1 2013 12:55 PM | Permanent Link |
Markku Nevalainen | There probably is some simple answer to this, but I just can't find it
in the EWB documentation nor from the newsgroup. procedure TForm1.Button1Click(Sender: TObject); begin if Sender = Button1 then Label1.Caption := 'Hello Btn1' else if Sender = Button2 then Label1.Caption := 'Hello Btn2' end; procedure TForm1.Button2Click(Sender: TObject); begin (Sender as TButton).Caption := 'You pressed me'; end; Is there any way with EWB how you could use Sender parameter in this traditional Delphi manner? Looks like EWB does not like or recognize 'as' keyword nor 'Sender'. If not, what would be the suggested method to replace this functionality in EWB? Thanks Mats |

Walter Matte Tactical Business Corporation | Do the following... this is very Delphi... procedure TForm2.Button1Click(Sender: TObject); begin If Sender is TButton then TButton(Sender).Caption := 'Yes'; end; Walter Mats Nevalainen wrote: There probably is some simple answer to this, but I just can't find it in the EWB documentation nor from the newsgroup. procedure TForm1.Button1Click(Sender: TObject); begin if Sender = Button1 then Label1.Caption := 'Hello Btn1' else if Sender = Button2 then Label1.Caption := 'Hello Btn2' end; procedure TForm1.Button2Click(Sender: TObject); begin (Sender as TButton).Caption := 'You pressed me'; end; Is there any way with EWB how you could use Sender parameter in this traditional Delphi manner?

> Do the following... this is very Delphi... Thanks, that was exactly the trick that made it. The second problem related to this same matter is this: procedure TForm1.CheckBox1Click(Sender: TObject); begin if Label2.Font.Color= clRed then Label2.Font.Color := clBlack else Label2.Font.Color := clRed; end; procedure TForm1.Button1Click(Sender: TObject); begin CheckBox1.Checked := NOT CheckBox1.Checked; end; That works in Delphi, when I click Button1, the Checkbox.Checked state changes and the font color in Label2 changes. With EWB only the Checked state changes, but the Label2 color does not change, the event seems not Fire right. Any ideas for this? I am looping through controls with ControlCount, and would like to change several Checkboxes sates with one Button press. --- Some other observations about EWB: 1) There seems not be Format -function available, to format Strings etc? 2) In EWB I miss Delphi variable Types like TCurrency, to avoid floating point rounding errors. 3)IDE does not have Bookmarking capability, to be easily jump different locations in code. 4) Pressing CTRL-F to open Find functionality automatically picks the Word under cursor and places it to Find function. I would like to see this in EWB also, the current Paint+Copy+Paste is bit tedious. 5) If you want to for instance Left Align 5 different controls, then Delphi left aligns the controls according to the one that was first picked. EWB does not care which was first choosed, it always automatically aligns according to the leftmost control of those 5 controls. Not very handy. 6) The 912 pages "Elevate Web Builder Manual" is a bit clumsy when trying to learn and find different things. I start to get tired watching Adobe to slowishly scan this huge manual back and forth. It maybe would be better if it was splitted to 2..4 different manuals and sections. --- In general, its seems that you can do *something useful* with EWB. And time to time I'll continue spending some time evaluating more of it. I wonder if anyone would have some simple example how to connect EWB to MySQL database? Thanks for any answers and suggestions. Mats |

Yes, but the same content is presented inside EWB-IDE in Menu Help - Elevate Web Builder Manual, which is easy to navigate through tree structure and internal links. So I prefer that. |

The find is also quite a problem because I often go somewhere to find a variable or other name, copy it to clipboard, and then to get back to the function I was in I have to copy that to the clipboard and paste it to find it. Slight flaw there... Improved navigation would be good. I can understand this may not be a priority, but I wonder if there is a way to hook this so others could implement such functions. (More work to do the hooks of course!) /Matthew Jones/ |

Claudia Borsel | This Pascal-IDE is open source and has all the bells and whistles one could ask for:
http://www.pilotlogic.com/sitejoom/index.php/codetyphon/codetyphon-download But unfortunately it can compile only for native CPU and for Java-VM, but not into Java-Script. I don't know if it is possible to merge EWB into that IDE and keep EWB commercial at the same time. But the efforts spent into that IDE are huge and can not be reproduced by a one-man show (? actually I don't know the number of elevate developers) in EWB. |

> But the efforts spent into that IDE are huge Also this IDE itself is quite huge. Total 476 MB in ZIP format. The introduction does not say very much, so I installed it just to see what is it actually. Codetyphon seems to offer some new UI for Lazarus and other Pascal dialects. That was a bit too heavy and complicated for me, to start studying it as a new Editor for EWB use. My D7 editor does not like EWB's .wbs files that are not old good ANSI but Unicode files. > and can not be reproduced by a one-man show (? actually I don't know the > number of elevate developers) in EWB. Many Delphi developer companies in general are turning to be one man's showsIt is a bit hard to find anyone under 40 yrs and with with Delphi knowledge. Mats |

<< With EWB only the Checked state changes, but the Label2 color does not change, the event seems not Fire right.

It only allows for strings, though, in the form of '%s' placemarkers. This function is used internally by the translations in the framework. << 2) In EWB I miss Delphi variable Types like TCurrency, to avoid floating point rounding errors. >> There is no such thing in a web browser.
