How do I draw the selected list-box item in a different color?

Is is possible to change the item selection focus color and text color in a TListBox? When themes are not enabled in the project, or the list box style is set to owner-draw, the selection around the item is painted blue, which I believe is globally defined by the system's appearance settings. I would like to change the color of selected items to a custom color. So an example, the result would be something like this: Note the last listbox has been modified in Paint to illustrate the example. try this: procedure TForm1.ListBox1DrawItem(Control: TWinControl; Index: Integer; Rect: TRect; State:

How to set the client area (ClientRectangle) in a borderless form?

问题 I want to know if it's possible to set the client area of a borderless form. Say for example I define a form like so: Code public class MyForm : Form { public MyForm() { this.FormBorderStyle = FormBorderStyle.None; } } Result What I want to do is specify the client area, so that the form has a frame (like the standard windows frame, but custom drawn). Result Essentially, the blue area would become the non client area, and the gray area would remain as the client area. I have tried to set the

How do I enable double-buffering of a control using C# (Windows forms)? I have a panel control which I am drawing stuff into and also an owner-drawn tab control. Both suffer from flicker, so how can I enable double-buffering? In the constructor of your control, set the DoubleBuffered property, and/or ControlStyle appropriately. For example, I have a simple DoubleBufferedPanel whose constructor is the following: this.DoubleBuffered = true; this.SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint | ControlStyles.ResizeRedraw | ControlStyles.ContainerControl | ControlStyles

C#: TreeView owner drawing with ownerdrawtext and the weird black highlighting when clicking on a node

由 喜欢而已 提交于 2019-11-27 08:45:38
I set the DrawMode to OwnerDrawText and tacked on to the DrawNode event, added my code to draw the text the way I want and all works well save for some odd black selection highlighting when a node is selected. No problem, I added logic to check for if the node's state was highlighted and drew my own highlighting except the black highlighting gets added when a node is clicked, not just selected... The highlight gets drawn over by my rectangle once the mouse button is released but does get drawn and blinks...it's annoying. :/ Apparently I forgot to actually ask my question...How would one go

Delphi TListview OwnerDraw SubItems - change default font (it's bold somehow after you Draw on the canvas)

由 一个人想着一个人 提交于 2019-11-27 07:59:32
问题 If you use ownerdraw with a TListView, the subitems are all BOLD font style by default somehow, even if the listview font.style is set to [], for all the SubItems following a custom drawn one. A workaround I found is forcing the Style set in the CustomDrawSubItem event: ListView2.Canvas.Font.Style := [fsItalic]; ListView2.Canvas.Font.Style := []; (a simple call with [] won't work unless the default style is set to something other than [], because the SetStyle call doesn't think the style has

Simple TListView OwnerDraw Text Font Size and Color example?

问题 I am trying to owner draw a List View control in report-mode with 4 columns, using OnCustomDrawItem . When I try to change the Canvas.font.color, and that's all I do, I have no problems. If I set canvas.font.size, I find that there is no change in the size of the text drawn by the control. If I try to take over the painting of the text, from within OnCustomDrawItem, I find I can not. I am aware of how to use OnCustomDraw to draw in the background area, but I want to custom draw a listview
