ALClient | node client for interacting with Adventure Land | Game Engine library

In a 32-bit VCL Application in Windows 10 in Delphi 11 Alexandria, I select a ListItem in the OwnerDrawn TListView.OnDrawItem event handler and I want the ENTIRE UNINTERRUPTED row to be selected. Unfortunately, not the entire row gets selected, but only the caption-text portion of the row gets selected:

This is what I need to achieve:

This is the code of the form-unit:

I have a problem that docking form hides some other components inside of panel.

This is simple example of my problem: I have Panel1 with DockSite set to True. Inside Panel1 is Panel2. Panel2 alignts to client (Align=alClient). Inside Panel2 is memo field that is also aligned to client. It overlaps the entire Panel1. I have another form (Form2) that I want to dock to Panel1. But it overlaps entire Panel1 and hides memo filed. I want to overlap only part of Panel1 (width of the form) and move Panel2 to the rigth or to te left.

Main form:

I like to change the order of rows in a TGridPanel by clicking a button. The Gridpanel rows are dymamically created and contain a Panel with a manually docked form. The form has its own edit components and a Label with the index of the current row. The best way would be like this:

1. Mark the row by clicking it
2. Click a button "up" or "down".
3. The selected row moves up/down.
4. The Index of the row changes in the docked form.

Here is my attempt:

I have a TImage on a resizable Form, and I want it to resize when I resize the Form.

What I tried:

• enabling all Anchors options
• putting the TImage on a TPanel, and then setting both Panel and Image alignments to alClient
• Assigning new Width and Height in the Form's OnResize event

None of these does the job.

This is the default Form size. The TImage gets redrawn whenever any of the parameters on the left change, or if the image is zoomed in/out (using the mouse scroll wheel). On each redraw, the pattern repeats until it fills the full TImage.

And this is the Form after resizing. Notice that the image size remains unchanged.

Enabling the Stretch property does work, but it also scales the image's content, which I don't want.

How can I fix this?

I'm on Delphi 10.3

In a Delphi 10.4.2 win-32 VCL Application in Windows 10, I use several nested TPanel:

Paste these controls on an empty form:

After setting ListView in virtual mode ListView1.Selected.Top always returns 0. I'm using that property on double click on list view to show edit box at that position.

How can I resolve this?

Example of .pas and .dfm files are here. I want to open edit box on position where it is double clicked.

In a Delphi 10.4.2 Win32 VCL Application on Windows 10 x64, I use a TWebBrowser component to display local SVG files. The TWebBrowser component has these properties:

Assume the following situation:

• FrmBase has a TPanel named PnlClient, align alClient
• FrmDescendant inherits from FrmBase
• In FrmDescendant I change a PnlClient property
• In FrmDescendant I place another control (say another TPanel named PnlDescendant) on PnlClient and align it alClient.
  PnlDescendant now completely covers PnlClient
• I place lots of other components on PnlDescendant, not necessarily aligned, so I'm afraid to change PnlDescendant (e.g. setting align to alNone and resizing) and lose positions

How can I execute 'revert to inherited' for PnlClient?
There's nothing in the main menu, or in the popup menu for the controls in the Structure View...

Currently using Delphi 10.4.1 Sydney

I have got a form with a TImage on it. That TImage is set to Align=alClient, Stretch=True, Proportional=True and Center=True.

At runtime I load a bitmap into that TImage. It gets displayed a bit smaller than the original size but without distortion, as I expect it.

Now I want to get the coordinates of the pixel under the mouse when I press the Mouse button. This is the code assigned to im_Input.OnMouseDown:
