Removing a FMX control’s size restrictions

Delphi Haven – One rather annoying aspect of FMX’s evolution has been a restriction on control sizes. The most notorious case is probably TGroupBox, which in XE4′s iOS support was bizarrely matched to Safari’s toolbar (i.e., a standard control with a non-standard height), rendering the thing ...

InfoPower grid for FireMonkey – free with XE5

Delphi Haven – In case anyone interested in FMX isn’t aware, Woll2Woll’s InfoPower grid for FireMonkey can be got free with XE5. OK, no source, but it’s much, much better than the standard offering: If you want to see the Android targeting in action, Woll2Woll have a demo on Google Play ...

Working around an XE5/Mac menu issue

Delphi Haven – In XE5, if you try running the FMX ‘ActionsDemo’ sample project on OS X, you’ll quickly find an issue – the menu bar isn’t set up correctly: If you open up the menu designer in the IDE, you’ll find what should be happening is that the application menu gets four ...

FMX menu unfurling speed

Delphi Haven – A bit ago I posted a QC report complaining about the speed at which a nested FMX popup menu unfurls. Steps: Create a new FMX desktop application. Add a TPopupMenu to the form, then four items to the popup menu, the second parented to the first, the third to second and the fourth to the third. Add a ...

FMX/XE5 issue: new ShowModal overload poorly implemented

Delphi Haven – A few weeks ago Marco Cantù, the Delphi Project Manager, blogged about a new FMX ShowModal overload introduced in XE5. As Marco explained, the reason for this new overload is because a Windows-style ShowModal isn’t possible on mobile platforms. While his blog post met the odd objection in the ...

TAndroidPreferencesIniFile fix

Delphi Haven – Just a small note to say, if anyone has downloaded my Android SharedPreferences wrapper (more info here), I’ve just put up a small fix for the ReadBool method, so you might want to update from the trunk. Thanks goes to Orren Grushkin for reporting the bug.

StackOverflown

Delphi Haven – So… I was finally broken: I created a StackOverflow account. Annoyingly, a certain individual in particular is waaaayy too fast in answering most Delphi questions (genuine expertise + quick on the button = cheating, surely?)… so I started picking off Access ones instead (easy points ...

Pearls in the ‘nextgen’-ified RTL source

Delphi Haven – Back in September 2012, a post appeared in non-tech reporting Delphi’s PCRE wrapper to be many, many times slower than Python’s. With sample code attached, the problem was undeniable, though the immediate cause was soon identified: the Delphi wrapper’s failure to include a ...

FMX issue – inability to safely process paint messages immediately

Delphi Haven – There are times when you want to repaint a control immediately, typically to give an indication to the user that something is actually happening during a lengthy bit of processing. In the VCL, this is covered by a troika of methods on TControl: Invalidate posts a message to the event queue saying ...

A few XE5-related bits

Delphi Haven – With XE5 now out, I’ve updated my FMX TClipboard and Mac PDF writer code to compile with it, and in the case of the latter, also made an unrelated fix suggested by Sebastian Zierer. With respect to TClipboard, I must add the caveat that the Android implementation merely delegates to the ...

FMX TClipboard now supports iOS

Delphi Haven – I’ve just checked in a revision of my open source FMX TClipboard implementation that has an iOS backend. This supports the current rather than the FPC-based version of ‘Delphi for iOS’, however the Windows and OS X backends still compile with XE2 and above. In essence, the new code ...
