问题 I'm using a TListView in Firemonkey. On startup, I create 3 list view headers and keep references to them for future use (specifically inserting items below each header). FItemHeader:= LV.Items.Add; FItemHeader.Purpose:= TListItemPurpose.Header; FItemHeader.Text:= 'Items'; FChargeHeader:= LV.Items.Add; FChargeHeader.Purpose:= TListItemPurpose.Header; FChargeHeader.Text:= 'Charges'; FPaymentHeader:= LV.Items.Add; FPaymentHeader.Purpose:= TListItemPurpose.Header; FPaymentHeader.Text:= 'Payments

问题 I'm new to iOS, have been developing in Delphi for many years. I don't know FPC well and i find it very hard to figure out which classes are available on iOS. is there any FireMonkey classes for calling web services and parsing xml? 回答1: Yes you can call a webservice :) No it is not simple :( You need to access the iOS framework directly...

问题 I need to show custom data. For example I need to show a contact list with name, description, photo. And ideally I would also like to show custom data there, e.g. a button to launch telephone call. The default styles do not quite do what I want, but fairly close. Thus, as far as I can tell, TListBox could be a decent control for this if I could create custom styles? Is that possible? (Anotther problem of course is setting the values of the custom data controls.) 回答1: You should take a good

问题 I'm new to Delphi & in DelphiXE4 editor I am trying to make chessboard gui on form, using x64 TRectangle for board (alternate colors).

问题 Can someone please guide me in the right direction. I am attempting to create a Custom ListboxItem using Delphi XE4 for a iOS application. My goal output would be something along the lines of the photo above, where as I am currently stuck here (image below). I have been successful at dynamically generating a ListBoxItem and inserting an TLabel object, however, I am unable to change the 'fontColor' property of the TLabel to a desired color. I can code TLabel.Fontcolor := ClaBlue; But the color

问题 Is there any way to make the TMemo transparent in Delphi/iOS/FireMonkey? I don't see any way to edit styles myself when selecting + right-clicking the memo control... 回答1: Try removing memo's background on applying style event. procedure TForm1.Memo1ApplyStyleLookup(Sender: TObject); var BckObject: TFmxObject; begin BckObject := Memo1.FindStyleResource('background'); if Assigned(BckObject) and (BckObject is TSubImage) then begin TSubImage(BckObject).Source := nil; end; end; 回答2: You need to

问题 I have a TDataSource that is backed by a TClientDataset bound to a TStringGrid . I did this by right-clicking on the grid, selecting " Link to DB Datasource... ", and selecting the DataSource. This setup the LiveBindings for me. When I run the application, the grid only fills with 200 rows, even though there are 5000 records in the dataset. I'm unable to find any documentation regarding how to change the number of rows displayed or the proper way to allow the user to scroll through all of the

问题 According to release notes of Delphi XE2. FireMonkey may create HD application. HD stands for High Definition. Why HD? Can't VCL application create HD apps as FireMonkey? 回答1: Here is the documentation on Firemonkey, from it you can see several features. Compare normal TV to HD TV. Is like comparing the VCL to what Firemonkey can do. It's a Marketing term that I suspect will catch on as it, does highlight the power. HD Applications refer many of the features of Firemonkey but the following

问题 I sort of asked this question at the end of another post but feel this topic needs a question of its own... If I have created my own component with its own .style what is the correct procedure to merge that with the defined styles supplied with Delphi without modifying the defaults?
