GTK滚动条大小为gvim

标签: vim gtk themes

我设法让滚动条比平常小一点。但是,我无法将父窗口小部件缩放到正确的大小。下图显示了我的意思,并显示了〜/ .gtkrc-2.0的内容......

我错过了什么?

gvim image

这是一个可复制的〜/ .gtkrc-2.0片段:

style "neverness" {
    GtkScrollbar::activate-slider = 1
    GtkScrollbar::trough-border = 0
    GtkScrollbar::slider-width = 9
    GtkScrollbar::min-slider-length = 36
    GtkScrollbar::has-forward-stepper = 1
    GtkScrollbar::has-backward-stepper = 1
}

class "GtkScrollbar" style "neverness"
class "GtkHScrollbar" style "neverness"
class "GtkVScrollbar" style "neverness"

这不是由GTK +引起的;它是由vim引起的。

参见vim73 / src / gui.c:gui_init_check():

gui.scrollbar_width = gui.scrollbar_height = SB_DEFAULT_WIDTH;

该值来自gui.h:

#define SB_DEFAULT_WIDTH 16

稍后,gui_position_components()执行此操作:

gui.right_sbar_x = text_area_x + text_area_width;

gui_update_scrollbars()这样做:

gui_mch_set_scrollbar_pos(&wp->w_scrollbars[SBAR_RIGHT],
                          gui.right_sbar_x, y,
                          gui.scrollbar_width, h);

完成
gtk_form_move_resize(GTK_FORM(gui.formwin), sb->id, x, y, w, h);

GtkForm是一个在vim中实现的自定义小部件;见gui_gtk_f.c:

void
gtk_form_move_resize(GtkForm *form, GtkWidget *widget,
                     gint x, gint y, gint w, gint h)
{
    widget->requisition.width  = w;
    widget->requisition.height = h;

    gtk_form_move(form, widget, x, y);
}

稍后,gtk_form_position_child()中的代码只是抓取widget->请求并将其用于子项的分配。

GtkVScrollbar看到它被分配的水平空间超过了它所需的水平空间(即SB_DEFAULT_WIDTH = 16),并以其分配为中心。这是您在滚动条周围看到的额外空间。

Vim不应该调整小部件的内部 - >请求字段。相反,它应该在某处(可能在GtkFormChild结构中)存储所需的值并使用它们。除此之外,它应该能够使用GTK +自己的大小请求来获得滚动条的请求宽度。
