FMX
I have this weird bug in Delphi 13 FMX where the height of the controls is not correct, at app startup. procedure TForm1.AfterConstruction; begin inherited AfterConstruction; MakeDemoBubble; end; TAutosizeBoxText (based on TRectangle) is parented in a ScrollBox. It is set to Align=Top. procedure TForm1.MakeDemoBubble; begin mmoUserResponse.Text := ‘WhatsApp-like text bubble. ‘ + #13#10+ ‘Cool and […]
Android’s lifecycle model is a mess. The OS freely kills your process whenever it needs RAM, and you—the app developer—are expected to deal with the fallout. Android shifts its memory problems onto the app layer, leaving you to rebuild your internal state because the OS felt like freeing 200 MB. FireMonkey tries to give you
I needed (for a project I am working on) to obtain the default language for the operation system. Preferable it should be in “human” format like “English” instead of “En-US”. The AI lead me to strange paths. In the end it tuned out to be quite easy so I created these two function (now part
In FMX, unlike the VCL, the Visible property affects both design time and runtime when set in the Object Inspector. That’s why setting Visible:= False in FMX hides components in the Form Designer, which is a big inconvenience. If you edit the form at design time often, you can keep Visible:= True in the designer
Under FMX, TComponent.Visible effects also the design time! Read More »
VCL had a nice and uniform message box system. Most important (and convenient), the messages were blocking. Because of the Android platform which does not support asynchronous messages, all this is gone. So I document here the behavior of few different ways in which we can display message boxes in FMX. None is perfect (not
IDE Removed deprecated features: VCL Translation Support & Modeling Object Inspector – New string list editor Multiline string Editor Multiline string literals The Find in Files dialog now has a new Subdirectory exclude mask option, which excludes specific folders from being searched when using the Search in directories and Include subdirectories There are default exclusions
Even though there are a few tools for porting a project from the VCL (Visual Component Library) to FMX (FireMonkey) the process is not easy especially because not all VCL components have direct FMX equivalents. Some components require substitution, and some functionality must be reimplemented. The problem deepens with 3rd party VCL components. Tools for
After installing FMX and using it for a while I started getting a weird “ld.exe cannot find shlwapi.dll” message. There was nothing like this to be found on the internet! I posted a question of StackOverflow but people started to point in (as later turned out to be) totally wrong directions. The complete error msg
