VCL 形式的 PageControl 上带有锚点的错误自动缩放控件 [英] Wrong auto-scaling controls with anchors on PageControl in VCL form

问题描述

我在为不同的显示器 DPI 设置自动缩放表单上的控件时遇到问题.Rad Studio 10.2 东京.启用高 dpi"已开启.我在设计时将表单的 PixelsPerInch 设置为 96.我将 TPageControl 放在一个窗体上，在其中创建一个 TTabSheet 页面，在页面上放置一些控件并将它们的 Anchor 属性设置为 akRight(除了 akLeft 和 akTop).当程序在分辨率为 120 DPI 的显示器上运行时，这些控件的右边缘会出现超出 PageControl 的右边界之外，因此控件的右侧部分不可见.如果我关闭 akRight，则控件将正确缩放.但是我需要这些锚点在运行时正确调整表单的大小.如何解决问题?

I have problems with auto-scaling of controls on my form for different monitor DPI settings. Rad Studio 10.2 Tokio. "Enable high-dpi" is on. I set the form's PixelsPerInch to 96 at design time. I put TPageControl on a form, create a TTabSheet page in it, put some controls on a page and set their Anchor property to akRight (in addition to akLeft and akTop). When the program is run on a monitor with a resolution of 120 DPI right edge of those controls appear extended beyond the right boundary of PageControl, so that the right parts of controls are not visible. If I switch off the akRight, then the controls are scaled correctly. But I need those anchors to resize form correctly at run time. How to solve the problem?

PS 该错误已在 Rad Studio 10.3 中修复

推荐答案

我遇到了同样的问题，一个应用程序拥有无数 TPageControl 和 TEdit、TMemo 和其他高 dpi 模式下未对齐的控件.

I was facing the same problem with an application owning myriads of TPageControl's with TEdit's, TMemo's and other misaligned controls in high-dpi mode.

我解决这个问题的第一个方法是尝试将 TForm 传递给一个名为 FixFormScaling() 的过程，我打算在那里修复所有有问题的缩放问题.但是我失败了，因为包含的控件有许多不同的对齐方式，我无法在一个简短的过程中合理地处理这些问题.

My first approach to solve this was an attempt to pass the TForm to a procedure called FixFormScaling(), where I intended to fix all buggy scaling stuff. But I failed greatly, due to having many different alignments of the contained controls, which I could not handle reasonably in one short procedure.

第二种方法似乎有效:在每个 TTabSheet 上，我放置了一个具有以下属性的 TPanel:

Align=alClient
BevelOuter=bvNone
Name=pnlDpiHelper<NameOfTabsheet>
ShowCaption=False

我正在将所有其他控件(TEdit、TMemo 等)移到该 TPanel 上.在高 dpi 模式下的结果是现在一切似乎都正确缩放了！

I am moving all other controls (TEdit, TMemo, etc.) onto that TPanel. The result in high-dpi mode is that everything seems to be scaled correctly now!
